Key Reaction. The main reaction for converting oil to
biodiesel is called transesterification. The transesterification process
reacts an alcohol (like methanol) with the triglyceride oils contained in
vegetable oils, animal fats, or recycled greases, forming fatty acid alkyl
esters (biodiesel) and glycerin. The reaction requires heat and a strong
base catalyst, such as sodium hydroxide or potassium hydroxide. The
simplified transesterification reaction is shown below.

Triglycerides +
Free Fatty Acids (<4%) + Alcohol ——> Alkyl esters +

|
Pretreatment Reaction. Some feedstocks must be
pretreated before they can go through the transesterification process.
Feedstocks with less than 4% free fatty acids, which include vegetable
oils and some food-grade animal fats, do not require pretreatment.
Feedstocks with more than 4% free fatty acids, which include inedible
animal fats and recycled greases, must be pretreated in an acid
esterification process. In this step, the feedstock is reacted with an
alcohol (like methanol) in the presence of a strong acid catalyst
(sulfuric acid), converting the free fatty acids into biodiesel. The
remaining triglycerides are converted to biodiesel in the
transesterification reaction.

Process Description.
-
Acid
Esterification. Oil feedstocks containing
more than 4% free fatty acids go through an acid esterification
process to increase the yield of biodiesel. These feedstocks are
filtered and preprocessed to remove water and contaminants, and then
fed to the acid esterification process. The catalyst, sulfuric acid,
is dissolved in methanol and then mixed with the pretreated oil. The
mixture is heated and stirred, and the free fatty acids are converted
to biodiesel. Once the reaction is complete, it is dewatered and then
fed to the transesterification process.
-
Transesterification. Oil feedstocks containing
less than 4% free fatty acids are filtered and preprocessed to remove
water and contaminants and then fed directly to the
transesterification process along with any products of the acid
esterification process. The catalyst, potassium hydroxide, is
dissolved in methanol and then mixed with and the pretreated oil. If
an acid esterification process is used, then extra base catalyst must
be added to neutralize the acid added in that step. Once the reaction
is complete, the major co-products, biodiesel and glycerin, are
separated into two layers.
-
Methanol recovery. The methanol is typically
removed after the biodiesel and glycerin have been separated, to
prevent the reaction from reversing itself. The methanol is cleaned
and recycled back to the beginning of the process.
-
Biodiesel refining. Once separated from the
glycerin, the biodiesel goes through a clean-up or purification
process to remove excess alcohol, residual catalyst and soaps. This
consists of one or more washings with clean water. It is then dried
and sent to storage. Sometimes the biodiesel goes through an
additional distillation step to produce a colorless, odorless,
zero-sulfur biodiesel.
-
Glycerin refining. The glycerin by-product
contains unreacted catalyst and soaps that are neutralized with an
acid. Water and alcohol are removed to produce 50%-80% crude glycerin.
The remaining contaminants include unreacted fats and oils. In large
biodiesel plants, the glycerin can be further purified, to 99% or
higher purity, for sale to the pharmaceutical and cosmetic industries.
What
is "esterification"?
Esterification
is the chemical process of combining an alcohol and an acid which results in the formation of an ester.
Global Warming. The combustion of fossil fuels such as
coal, oil, and natural gas has increased the concentration of carbon
dioxide in the earth's atmosphere. The carbon dioxide and other so-called
greenhouse gases allow solar energy to enter the Earth's atmosphere, but
reduce the amount of energy that can re-radiate back into space, trapping
energy and causing global warming.
One environmental benefit of replacing fossil fuels with biomass-based
fuels is that the energy obtained from biomass does not add to global
warming. All fuel combustion, including fuels produced from biomass,
releases carbon dioxide into the atmosphere. But, because plants use
carbon dioxide from the atmosphere to grow (photosynthesis), the carbon
dioxide formed during combustion is balanced by that absorbed during the
annual growth of the plants used as the biomass feedstock—unlike burning
fossil fuels which releases carbon dioxide captured billions of years ago.
You must also consider how much fossil energy is used to grow and process
the biomass feedstock, but the result is still substantially reduced net
greenhouse gas emissions. Modern, high-yield corn production is relatively
energy intense, but the net greenhouse gas emission reduction from making
ethanol from corn grain is still about 20%. Making biodiesel from soybeans
reduces net emissions nearly 80%. Producing ethanol from cellulosic
material also involves generating electricity by combusting the
non-fermentable lignin. The combination of reducing both gasoline use and
fossil electrical production can mean a greater than 100% net greenhouse
gas emission reduction. In the case of ethanol from corn stover, we have
calculated that reduction to be 113%.
Vehicle Emissions. Petroleum diesel and gasoline
consist of blends of hundreds of different hydrocarbon chains. Many of
these are toxic, volatile compounds such as benzene, toluene, and xylenes,
which are responsible for the health hazards and pollution associated with
combustion of petroleum-based fuels. Carbon monoxide, nitrogen oxides
sulfur oxides and particulates, are other specific emissions of concern. A
key environmental benefit of using biofuels as an additive to
petroleum-based transportation fuels is a reduction in these harmful
emissions.
Both bioethanol and biodiesel are used as fuel oxygenates to improve
combustion characteristics. Adding oxygen results in more complete
combustion, which reduces carbon monoxide emissions. This is another
environmental benefit of replacing petroleum fuels with biofuels. Ethanol
is typically blended with gasoline to form an E10 blend (5%-10% ethanol
and 90%-95% gasoline), but it can be used in higher concentrations such as
E85 or in its pure form. Biodiesel is usually blended with petroleum
diesel to form a B20 blend (20% biodiesel and 80% petroleum diesel),
although other blend levels can be used up to B100 (pure biodiesel).
What
is B2 Biodiesel?
Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, home-grown fuel
that replaces petroleum diesel. When blended with equal parts of
B100 biodiesel, creates B50 biodiesel, or 50% biodiesel and 50% petroleum
diesel. Therefore, B2 Biodiesel, is comprised of a "blend" of 2%
Biodiesel and 98% petroleum diesel.
What
is B5 Biodiesel?
Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, home-grown fuel
that replaces petroleum diesel. When blended with equal parts of
B100 biodiesel, creates B50 biodiesel, or 50% biodiesel and 50% petroleum
diesel. Therefore, B5 Biodiesel, is comprised of a "blend" of 5%
Biodiesel and 95% petroleum diesel.
What is B10 Biodiesel?
Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, domestic fuel that
when blended with 9 parts petroleum diesel to one part biodiesel creates
B10 biodiesel, or 20% biodiesel and 80% petroleum diesel.
What is B20 Biodiesel?
B20 Biodiesel is one the most popular biodiesel blends
presently available thoughout much of the U.S., Canada and Europe. Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, domestic fuel that
when mixed with four parts petroleum diesel to one part biodiesel creates
B20 biodiesel, or 20% biodiesel and 80% petroleum diesel.
What
is B50 Biodiesel?
Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, domestic petroleum
diesel when blended with equal parts of B100 biodiesel creates B50
biodiesel, or 50% biodiesel and 50% petroleum diesel.
What is B95 Biodiesel?
Pure biodiesel or B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, home-grown fuel
that replaces petroleum diesel. When blended with equal parts of
B100 biodiesel, creates B50 biodiesel, or 50% biodiesel and 50% petroleum
diesel. Therefore, B95 Biodiesel, is comprised of a "blend" of
95% Biodiesel and 5% petroleum diesel.
What is B99 Biodiesel?
Pure biodiesel or
B100 Biodiesel, is a non-toxic,
biodegradable, renewable, carbon-neutral, sulfur-free, home-grown fuel
that replaces petroleum diesel. When blended with equal parts of
B100 biodiesel, creates B50 biodiesel, or 50% biodiesel and 50% petroleum
diesel. Therefore, B99 Biodiesel, is comprised of a "blend" of
99% Biodiesel and 1% petroleum diesel.
What is B100 Biodiesel?
Pure biodiesel is referred to as B100 Biodiesel, which is
a non-toxic, biodegradable, renewable, carbon-neutral, sulfur-free,
domestically "grown" biofuel. B100 Biodiesel is refined from
many American-grown fuel/energy crops such as soybeans, canola, rapeseed
and even palm trees.
Can B20 Biodiesel cause, or prevent problems
for my diesel engine?
This depends on the age of the car. Biodiesel is a solvent and
may affect some seals, gaskets, and adhesives, particularly those made before 1993 and those
made from natural or nitrile rubber. Most diesel engines manufactured
after 1994 have been constructed with gaskets and seals that are biodiesel resistant. Earlier engine
models or rebuilds may use older gasket and seal materials and present a risk of swelling,
leaking, or failure. Fuel pumps may contain rubber valves that may fail.
B20 Biodiesel cleans dirty engine deposits, which may result in you needing an initial fuel filter change.
B20 Biodiesel fuel is being widely used in various areas around the United
States and Canada. Its production and distribution is expanding rapidly
throughout the U.S. and Canada.
Now that B20 Biodiesel has been gaining wide-spread
distribution and popularity, questions are being asked for which some of
the more common questions are answered below.
Does B20 Biodiesel perform as well as regular petroleum diesel?
Yes! In most cases you will not be unable to tell the difference between the two
fuels, although some notice the diesel exhaust lightening in color due to the reduced
emissions. B20 Biodiesel can be used in existing engines and fuel
injection equipment with little impact to operating performance. In more than 30 million miles of in-field
demonstrations, B20 has produced similar fuel consumption, horsepower, torque, and haulage rates as
conventional diesel fuel. B20 Biodiesel also has superior lubricity, which helps prevent
engine wear, plus it has a higher cetane number than U.S. diesel fuel, which classifies
B20 as a premium grade fuel.B20 has a BTU content that falls in the range between
#1 and #2 diesel fuel.
How does B20 Biodiesel fuel get shipped
and distributed?
B20 Biodiesel is shipped throughout the U.S. and Canada as B100 Biodiesel. Once
it arrives in at our partner company's bulk fuel facilities, it is mixed
in various ratios of between 20%-80% with petroleum diesel. To
produce B20 Biodiesel, we blend one part of B100 Biodiesel with 4 parts of
petroleum diesel. The blended B20 Biodiesel is then delivered to our fuel users and public sales points
throughout the U.S. and Canada.
Can I use B20 Biodiesel during the winter
and long periods of cold weather?
Yes! In fact, B20 Biodiesel has almost the same cold weather properties as regular
petroleum diesel. B20 Biodiesel is used throughout the U.S. National Parks
Services, including cold-weather climates such as Yellowstone National Park,
without any problems or complaints.
Clean the Air We
Breathe!
B20 Biodiesel burns significantly cleaner than regular petroleum diesel. This means
engines in cars powered by B20 Biodiesel fuel will significantly fewer harmful exhaust
emissions than those of regular petroleum diesel. In fact, the higher the percentage of
biofuel used, the greater the reduction in dangerous emissions.
More specifically, the B20 Biodiesel fuel used in your diesel engine means you are
reducing the amount of harmful emissions from your car or truck into our air by the following amounts:
• Carbon monoxide -12.6%
• Hydrocarbons -11.0%
• Particulates -18.0%
• Air toxics -12%–20%
• Mutagenicity -20%

At an average production rate of 130
gallons per acre, Canola or Rapeseed Oil ("BioDiesel") is one of
the preferred energy crops in the U.S. and Europe.
What is Canola Biodiesel?
Canola biodiesel is an environmentally- friendly, renewable energy source that could also produce cost savings for taxpayers and private
businesses and is produced from farmers that grow canola.
Biodiesel produced from canola and rapeseed oil is superior to soy biodiesel.
Especially due to the widely varying price fluctuations of soybeans. And
because the feedstock (the oil produced from the fuel crop, such as
soybeans, rapeseed or canola) to make biodiesel makes up about 80% of the
cost for
100 % biodiesel, basic economics dictate that the feedstock be obtained
from the least-cost source, which is going to be either canola or
rapeseed.
Initial research conducted by the University of Saskatchewan and the AAFC Saskatoon Research Centre has found that each ton of renewable biodiesel fuel saves five times its weight in diesel fuel. As well, engines using biodiesel demonstrate wear rates as much as 50% lower than those using regular commercial fuels – effectively doubling engine life.
Canola is a member of the Brassica Family, which includes broccoli, cabbage,
cauliflower, mustard, radish, and turnip. It is a variant of the crop rapeseed. Grown for its seed, the seed
is crushed for the oil contained within. After the oil is extracted, the by-product is a protein-richmeal used by the intensive livestock industry.
Canola is a very small seed, which means sowing depth must be controlled.
The current sowing practice is to cover the seed lightly with soil, which
provides more protection from drying out after germination.
Canola is generally sown in autumn and develops over winter, with flowers
emerging in the spring and is harvested early summer. With a growing
period of around 180-200 days climatic effects such as sudden heat waves can reduce yields and hot dry conditions can
limit its oil content. Summer weather ensures low moisture (less than 6%) at harvest. Carry-in
stocks of canola are minimal because of a lack of on-farm storage. Canola is a good rotational crop, acting as a break crop for cereal root diseases. However
for disease-related reasons, a rotation period of 3-5 years is required for canola crops.
of iodine in grams absorbed per 100 ml of oil is then the IV. The higher the IV, the
more unsaturated (the greater the number of double bonds available) is the oil and the higher
the potential to ‘gum up’ when used as a fuel in an engine. Though some oils have a low IV and are suitable without any further processing other
than extraction and filtering, the majority of vegetable and animal oils have an IV which does
not permit their use as a neat fuel.
Generally speaking, an IV of less than about 25 is required if the neat oil is to be used
in unmodified diesel engines and this severely limited the types of oil that can be used.
The IV can be easily reduced by hydrogenation of the oil (reacting the oil with hydrogen),
the hydrogen breaking the double bond and converting the fat or oil into a more saturated oil
and reducing the tendency of the oil to polymerise. However this process also tends to increase
the melting point of the oil and converts the oil into margarine. Only coconut oil has an IV low enough to be used without
any special precautions in a unmodified diesel engine. However with a melting point of 25°C,
the use of coconut oil in cooler areas would obviously lead to problems.
Linseed oil could be mixed with petroleum diesel at a
ratio of up to 1:8 to give an equivalent IV in the mid-twenties. Likewise coconut oil can be thinned with diesel or kerosene to render it less viscous in cooler climates. Obviously
the solubility of the oil in petroleum also needs to be taken into account. Another method is
to emulsify the oil or fat with ethanol. Most vegetable oils are a mixture of different esters such as oleic acid (main constituent
of olive oil), ricinoleic acid (main constituent of castor oil), linoleic acid
(main constituents of linseed oil), palmitic acid (main constituent of palm kernel oil) and so on.
In an analogous way to that in which crude oil is refined to make a useable automotive
fuel, canola oil needs to be transesterified to make an automotive fuel that is useable in
unmodified diesel engines.
When the oil is processed in a transesterfication process, the various fatty
acids react with the alcohol to form a mixture of lighter esters and glycerol. The name of
the specific fuel is called after the plant (or animal) source plus the alcohol. Made from
rapeseed oil and methanol, the biodiesel is called Rape Methyl Ester (RME), from canola oil
and ethanol, Canola Ethyl Ester (CEE), and from used McDonald’s cooking oil and ethanol
or methanol, ("McDiesel").
What is Rapeseed Biodiesel?
Rapeseed, some varieties of which are used to make mustard and others to make canola oil, is the preferred biodiesel feedstock in Europe.
Depending on the variety, rapeseed oil contains about 40 to 50 percent of
its weight in rapeseed is oil, as compared with only 20 percent for soybeans. It can be planted and harvested with the
same equipment used for small grains. In addition, rapeseed oil offers certain advantages in the production of biodiesel.
What is "Global
Warming Potential?
Global Warming Potential (GWP) is the index used to translate the level of emissions of various gases into a common measure in order to compare the relative radiative forcing of
different gases without directly calculating the changes in atmospheric concentrations.
GWPs are calculated as the ratio of the radiative forcing
that would result from the emissions of one kilogram of a greenhouse gas to that from emission of one kilogram of carbon dioxide over a period of
time (usually 100 years). Gases involved in complex atmospheric chemical processes have not been assigned GWPs due to complications that arise.
Greenhouse gases are expressed in terms of Carbon Dioxide Equivalent. The International Panel on Climate Change (IPCC) has presented these GWPs
and regularly updates them in new assessments. The instantaneous radiative forcing that results from the addition of 1 kilogram of a gas to the
atmosphere, relative to that of 1 kilogram of carbon dioxide.
Over a time horizon of 100 years, methane has a GWP of 24.5, nitrous oxide has a GWP
of 320, and CFC-11 has a GWP of 4,000
What Are Greenhouse Gases?
Some greenhouse gases occur naturally in the atmosphere, while others result from human activities. Naturally
occurring greenhouse gases include water vapor,
carbon dioxide, methane, nitrous oxide, and ozone. Certain human activities, however, add to the levels of most of these naturally occurring gases:
Carbon dioxide is released to the atmosphere when solid waste, fossil fuels (oil, natural gas, and coal), and wood and wood products are burned.
Methane is emitted during the production and transport of coal, natural gas, and oil. Methane emissions also result from the decomposition of organic wastes in municipal solid waste landfills, and the raising of livestock. More information on methane.
Nitrous oxide is emitted during agricultural and industrial activities, as well as during combustion of solid waste and fossil fuels.
Very powerful greenhouse gases that are not naturally occurring include hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6), which are generated in a variety of industrial processes.

What are Nitrogen Oxides?
Nitrogen oxides, or NOx, is the generic term for a group of highly reactive gases, all
of which contain nitrogen and oxygen in varying amounts. Many of the
nitrogen oxides are colorless and odorless. However, one common pollutant,
nitrogen dioxide (NO2) along with particles in the air can
often be seen as a reddish-brown layer over many urban areas.
Nitrogen oxides form when fuel is burned at high temperatures, as in a
combustion process. The primary sources of NOx are motor vehicles,
electric utilities, and other industrial, commercial, and residential
sources that burn fuels.

Reasons for Concern
|
Nitrogen
Oxides
-
are
one of the main ingredients involved in the formation of
ground-level ozone, which can trigger serious respiratory
problems.
-
reacts to form nitrate particles, acid aerosols, as well as
NO2, which also cause respiratory problems.
-
contributes to formation of acid rain.
-
contributes to nutrient overload that deteriorates water
quality.
-
contributes to atmospheric particles, that cause visibility
impairment most noticeable in national parks.
-
reacts to form toxic chemicals.
-
contributes to global warming.
NOx and the pollutants formed from NOx
can be transported over long distances, following the
pattern of prevailing winds in the U.S. This means that problems
associated with NOx are not confined to areas where NOx are
emitted. Therefore, controlling NOx is often most effective if
done from a regional perspective, rather than focusing on sources
in one local area.
NOx emissions are increasing.
Since 1970, EPA has tracked emissions of the six principal air
pollutants - carbon monoxide, lead, nitrogen oxides, particulate
matter, sulfur dioxide, and volatile organic compounds. Emissions
of all of these pollutants have decreased significantly except for
NOx which has increased approximately 10 percent over this period
|
How can Nitrogen Oxides be Removed from the
Environment?
Selective Catalytic Reduction (SCR) is a proven and effective method to reduce nitrogen
oxides which is an air pollutant associated with the power generation
process. Nitrogen oxides are a contributor to ground level ozone.
How does Selective Catalytic Reduction work?
SCR Systems work similar to a catalytic converter used to reduce automobile emissions. Prior to exhaust gases going up the smokestack, they will pass through the SCR
System where anhydrous ammonia reacts with nitrogen oxide and converts it to nitrogen and water.
