COMBUSTIBLE COMPOSITIONS CONTAINING GAS OIL AT LEAST ONE FATTY ACID ESTER AND AN N-BUTANOL-BASE ALCOHOL CONSTITUENT WHICH CAN BE FOR USE IN PARTICULAR AS DIESEL FUELS

摘要

A combustible composition that is particularly suitable as a diesel fuel comprises from 10 to 60% by volume of at least one gas oil; from 10 to 60% by volume of at least one C1-8 alkyl ester of a C12-22 fatty acid; and from 10 to 50% by volume of a mixture containing at least n-butanol and acetone. The mixture may also contain 1 to 15% by weight of methanol. The ester in the composition may be prepared by transesterifying natural fatty materials. Cetane-number- improving additives may be added, especially when the cetane number would otherwise be below 40.
