Abstract: Biodiesel is a new and sustainable potential source for bioenergy industry.
Currently, biodiesel is produced using easily available edible vegetable oils from
the agricultural industry but the use of edible oils for the production of biodiesel
being in direct competition with food; it is simply not possible to justify the utilization
of vegetable oils for the production of biodiesel. It is in this context that efforts have
been made to make use of non-edible oil yielding Hemp (Cannabis sativa L.) plant
for biodiesel production. The Free Fatty Acids content of crude Hemp plant oil was
reduced from 47.15 mg KOH/g to 1.01 mg KOH/g by the process of esterification
before the synthesis of biodiesel. The highest conversion percentage of biodiesel
i.e. 83.41% and 85.44% was obtained against NaOH and KOH in concentration of
0.75% (w/w)) and (1.0% (w/w)), respectively. The various reaction of synthesis
parameters such as temperature, time of reaction, steering speed and oil molar
ratio were adjusted to 60 oC, two hours, 600 rpm and 1:6, respectively. Available
analytical techniques were used for qualitative authentication. GC-MS was used for
profiling of various fatty acid methyl esters, FT-IR to monitor the synthesis reaction
and C & H NMR for justification of carbon and proton of the specified compound.
The fuel properties of biodiesel were tested and compared with EN and ASTM
standards.
