The Fuel That Comes from Vegetables -
Bio-diesel Fuel
Bio-diesel
fuel is the name given for a clean burning methanol or
ethanol-based fuel made from vegetable or animal fats. It can
function as diesel engines without alteration and is also a
possible entrant to replace fossil fuel as the world's primary
transport energy source.
This fuel starts out at vegetable based oil.
The oil is chemically changed into methyl esters or the
bio-diesel and glycerin (a byproduct). The chemical procedure
for this is called transesterfication. You can make biodiesel
from new oil, but often the biodiesel originally started as
waste oil from restaurants and even at home.
Bio-diesel can be blended in any amount with
petroleum based diesel fuel even though it as a disadvantage of
corrupting rubber gaskets and hoses in vehicles. Bio-diesel is
a better solvent than petro-diesel and has been known to
rupture down deposits of residue in the fuel lines of vehicles
that have previously been run on petroleum. Fuel filters may
become clogged with particulates if a quick transition to pure
bio-diesel is made, but bio-diesel cleans the engine in the
process.
In a research conducted at U.S. military
base, a bio-diesel blend was used as a substitute for heating
oil at housing on the base. Due to the solvent power of
bio-diesel, residues that had been present in fuel tanks for
decades were dissolved. The particulate component of the
residues caused frequent clogging of fuel strainers, requiring
repeated replacement, cleaning, and in some cases installation
of higher capacity filters. Due to the relatively smaller
surface area and service life of fuel tanks in motor vehicles
and mobile equipment, filter clogging is less prevalent but
still a factor to be considered.
Generally, bio-diesel is more costly to
acquire than petroleum diesel, although this gap may reduce due
to economies of scale, the rising cost of petroleum, and
government subsidization favoring the use of
bio-diesel.
The good thing about bio-diesel is, it has
benefits in comparison with petroleum-based fuel. This
includes:
•Bio-diesel reduces emissions of carbon
monoxide (CO) by roughly about 50% and carbon dioxide by
78.45% on a net lifecycle basis because the carbon in
biodiesel emissions is cast-off from carbon that was
already in the atmosphere, rather than being new carbon
from petroleum that was sequestered in the earth's
crust.
•This fuel contains fewer aromatic
hydrocarbons: benzofluoranthene: 56% reduction and
Benzopyrenes: 71% reduction.
•This fuel also removes sulfur emissions
(SO2), because bio-diesel does not have sulfur.
•Bio-diesel fuel reduces by as much as
65% the emission of particulates, small particles of solid
combustion products.
•Bio-diesel fuel does produce more no
emissions than petrodiesel, but these emissions can be
lessening through the use of catalytic
converters.
•This fuel is biodegradable. It can be
used as a clean-up technology with oil spills.
•Non toxic in small
quantities.
•This is safer to use than
diesel.
•Bio-diesel fuel has already been proven
as an excellent lubricity additive.
•Federal tax incentives could make low
blends economical for refiners to incorporate bio-diesel as
a lubricity additive.
Now, after knowing the benefits of
this fuel, it is also a must that you know the things to
consider when storing a bio-diesel.
1. Check storage tank for water prior to
introducing bio-diesel.
2. The bio-diesel fuel should be used
within six months.
3. Bio-diesel will increase the cold flow
properties of the blended fuel. Your distributor can manage
this by adding additives or kerosene.
4. Brass, bronze, copper, lead and zinc
will cause biodiesel to oxidize and create sediments.
Replace with stainless steel or
aluminum.
