COMBUSTIBLE COMPOSITIONS COMPRISING ALCOHOLS AND FATTY ACID ESTERS USEFUL IN PARTICULAR AS DIESEL FUELS

摘要

Combustible compositions, particularly diesel fuels, comprise a stable mixture of from 50 to 90% by volume of at least one C1-8 alkyl ester of a C12-22 fatty acid, and from 50 to 10% by volume of at least one alcoholic constituent comprising at least one primary, secondary or tertiary aliphatic monohydric C1-5 alcohol. The esters can be obtained by transesterifying certain natural oils and fats; the alcohols by fermentation. The compositions may contain a cetane-number-improving additive, especially if their cetane number does not otherwise exceed 40.
