Transesterification of Pongamia pinnata Oil Using Base Catalysts: A Laboratory Scale Study
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 1
Abstract
Pongamia pinnata is a deciduous, salt tolerant, drought resistant nitrogen fixing leguminous tree and their seeds are well known for extraction of non-edible oil. In the present study, the crude oil extracted from Pongamia pinnata seed was used to synthesize biodiesel (fatty acid methyl esters) by tranesterification with methanol in the presence of two different base catalysts viz. NaOH and KOH at a predetermined optimum temperature of 60˚C, stirring speed of 300 rpm for 45 minutes. A percentage conversion of 68% and 73% respectively was achieved by NaOH and KOH catalyzed transesterification reaction. Further, fuel properties of the transesterified oil (biodiesel) obtained using the two catalysts were compared with crude Pongamia oil and a biodiesel blend (B20). Fuel properties taken into consideration were density, viscosity and flash point.
