Abstract

Jatropha curcas oil is a renewable source of biodiesel fuel with no competing food uses. Crude Jatropha oil has high contents of free fatty acid (FFA) and water, which decrease the yield and quality of the product biodiesel in industrial production processes. A bench-scale production system connected the expanded-bed reactor packed with the cation-exchange resin and that packed with an anion-exchange resin in series was constructed. The cation-exchange resin had a catalytic ability to convert FFA to biodiesel by esterification reaction without inhibition by water. The anion-exchange resin had a catalytic ability to convert glycerides to biodiesel by transesterification reaction without soap formation as well as an absorbent ability to remove impurities, e.g., glycerin, water, and pigment contained in the product. High quality biodiesel fuel would be produced from the crude Jatropha oil without any pretreatment of the raw oil and the purification of the products. This is an abstract of a paper presented at the 2011 AIChE Annual Meeting (Minneapolis, MN 10/16-21/2011).
