• Pakistan consumes around 8 million tons of diesel
per annum
• Imports 3.4 million tons
• Vegetable oils as raw material can lead to thickening in cold climate, fuel flow
problems, poor atomization and low efficiency
• Higher engine power than conventional diesel fuel
• Lower carbon dioxide, carbon monoxide, hydrocarbons and smoke emissions
• Similar properties as that of diesel but green fuel
PROCESS FLOW DIAGRAM
• Less expensive method yet useful and environmental
friendly
• Free fatty acid contents reduced to 1%
• Insulation of storage tanks and pipe-lines would need to
be done at low temp zone.
• Polluted water needs to be treated first and then used
• Storage tanks made of aluminum, steel etc. are
recommended for usage.
World’s fossil fuel energy sources crisis to explore
renewable energy sources which are more energy
efficient & environmental friendly.
Jatropha is a bush that grows in regions around the
equator as raw material to convert it into biodiesel
by Base Catalyzed Trans-esterification reaction.

Biodiesel can be used to regulate oil crop

Neat biodiesel is as biodegradable as sugar
and less toxic than salt
Biodiesel is also a job creator
ABSTRACT
OBJECTIVES
FEASIBILITY
Substitute
• Substitution
fuel for
petroleum-
derived
diesel and
can be used
in existing
diesel
engine
without
modification
Commercialize
• Glycol
formed
reduce the
final
manufacturi
ng costs of
the process
up to 6.5 per
cent.
LowPrice
• Jatropha oil
produced on
commercial
basis is less
costly
