Comparative study between microwave assisted extraction and soxhlet extraction techniques for bio-oil extraction from Jatropha curcas

Microwave assisted extraction (mae) was used to obtain crude oil from jatropha curcas seeds. the sample were extracted at different volume of water that act as solvent (50 ml,100 ml,150 ml and 200 ml) the oil yield obtained was compared with the soxhlet extraction (se) oil yield. the yield from mae at 50 ml,100 ml,150 ml,and 200 ml was 19%,31%,33%,and 40% respectively. the aromatic compound was present in the mae extracted oil but was not found in se extracted oil. there is a major disruption in alkanes group as sample was analysed before and after extraction. mae is more favourable compared to se as it do not consumed hazardous organic solvent,low cost and has extremely shorter extraction time compared to se. © school of engineering,taylor’s university.
