Abstract
This process consists in adding to gas oil from 100 to 5000 ppm of water in the form of a micellar clear and limped solution, which is stable for long times, obtained by the addition of one or more surfactants, associated with one or more auxiliary surface-active agents (co-surfactants). This invention substantially improves the combustion of gas oils.

Process for improving the combustion of a gas oil comprising incorporating into said fuel from 100 to 5000 ppm of water in conjunction with at least one surfactant of the formula:
- ##STR6## wherein Z represents CO or SO.sub.2, n is an integral number from 1 to 6, R is an alkyl group or a hydrogen atom, R' is an alkyl or alkenyl group, a hydrogen atom or an acyl group, while R" is methyl or is absent, or a salt thereof.
A gas oil composition comprising hydrocarbons boiling between 200.degree. and 425.degree. C., having improved combustion properties, which contains 100 to 5000 ppm of emusified water and 10 to 5000 ppm of at least one surfactant of the formula ##STR8## wherein Z represents CO or SO.sub.2, n is an integral number from 1 to 6, R is an alkyl group or a hydrogen atom, R' is an alkyl or alkenyl group, a hydrogen atom or an acyl group, while R" is methyl or is absent or a salt thereof.
