Biodiesel is renewable, eco-friendly, clean burning diesel replacement that is consisted of short chain alkyl ester. Biodiesel is derived from the transesterification of vegetables oils or animal fats with alcohol. The process has some technical problems that must be resolved to reduce the high operation cost. Eco-friendly physical technologies by using microwave have successfully improved the trans-esterification or esterification for biodiesel production. This study examined the effect of a solid acid catalyst on the esterification of fatty acid oil assisted by microwave irradiation. A solid acid catalyst was prepared by sulfonating pyrolyzed sawdust, empty fruit bunch (EFB) with concentrated sulfuric acid. The fatty acid methyl ester (FAME) of the biodiesel obtained has been confirmed by GC analysis of the isolated product. |
