Biodiesel production from crude Jatropha curcas L. seed

A technique to produce biodiesel from crude Jatropha curcas seed oil (CJCO) having high free fatty acids (15%FFA) has been developed. The high FFA level of JCJO was reduced to less than 1% by a two-step pretreatment process. The first step was carried out with 0.60 w/w methanol-to-oil ratio in the presence of 1% w/w H 2 SO 4 as an acid catalyst in 1-h reaction at 50 °C.

Jatropha curcas seeds afford non edible oil seed source for biodiesel, therefore, production of biodiesel from this oil would avoid food versus fuel controversy. However, Jatropha seed oil contains higher amounts of free fatty acids (about 12%). Therefore this requires a two step acid-base catalyzed treatment for the trans-esterification to obtain biodiesel.
