METHOD FOR PRODUCTION OF BIODIESEL FUEL, AND BIODIESEL FUEL COMPOSITION

摘要

[PROBLEMS] To provide a biodiesel fuel having excellent oxidation stability, and to provide a novel technique for producing a mixture of biodiesel fuel having excellent oxidation stability and a light oil. [MEANS FOR SOLVING PROBLEMS] An fatty acid alkyl ester (1) prepared from a transesterified oil-and-fat and/or a transesterified waste cooking oil and/or a fatty acid alkyl ester (2) prepared by esterifying a fatty acid are hydrogenated in the presence of a hydrogenation catalyst comprising at least one element selected from rare earth elements and at least one noble metal selected from noble metals belonging to Group VIII on the periodictable in a hydrogen atmosphere under a low pressure. A light oil may be added to the fatty acid alkyl ester (1) and/or the fatty acid alkyl ester (2).
