Title: Green synthesis of biodiesel through lipase mediated transesterification of non-conventional oils and exhaust emission studies
Abstract:
An increased interest in
reducing the dependability on petroleum based diesel fuel, reducing the exhaust
emission levels and improving the quality of air has led to many researches on
designing a paramount method for biodiesel production which is an alternative
energy source. In the present study,
experimental results from chemical mediated as well as lipase mediated methods
were compared by using common influencing parameters such as methanol/oil molar
ratio, catalyst concentration, reaction time and reaction temperature.
Biodiesel conversion of 96% was achieved by alkali mediated
transesterification, whereas the conversion rate was 87% for lipase mediated
method. The results of field experiments of exhaust emission studies by using
different blends of biodiesel gave the impression that usage of Lewatit
immobilized lipase for the biodiesel production from used cooking oil was
superior method as compared to KOH mediated biodiesel production. The biodiesel
production process was further improved by immobilizing the lipase on different
types of nanoparticles thus developing a nanobiocatalyst. The average
percentage reduction of 57.2% and 54.7% in the emissions of CO and PM,
respectively was observed in the biodiesel blend B100.
