Abstract
A method for producing diesel grade fuel of plant origin by transesterifying a refined vegetable oil with a charge of a C1-C4 alcohol in the presence of a catalyst and at least 0.2 parts by volume, related to unit volume of refined vegetable oil, of an aliphatic hydrocarbon solvent with a boiling point of −42° C. to 200° C., comprises mixing the oil, alcohol, catalyst and solvent in a single reaction vessel under homogeneous conditions which promote transesterification to 95-98% completion and which suppress reverse glycerolysis, without stopping transesterification to remove by-product polar glycerol, and without subjecting the oil/fuel mixture to a further transesterification step with a fresh charge of alcohol and catalyst.
IPC Classes ?
- C10L 1/18 - Organic compounds containing oxygen
- C11C 3/00 - Fats, oils or fatty acids obtained by chemical modification of fats, oils or fatty acids, e.g. by ozonolysis
- C10L 1/02 - Liquid carbonaceous fuels essentially based on components consisting of carbon, hydrogen, and oxygen only
- C11C 3/06 - Fats, oils or fatty acids obtained by chemical modification of fats, oils or fatty acids, e.g. by ozonolysis by esterification of fats or fatty oils with glycerol
