Abstract:
An emulsified fuel containing a major portion of hydrocarbon liquid and a minor portion of from 5 to 35% by weight water, containing a set of additives including an emulsifying system comprising:i) from 2.5 to 3.5 parts by weight of at least one sorbitol ester of formula (I) below: in which the radicals X are identical or different and each correspond to a group selected from OR1 groups, R1 being hydrogen or an aliphatic radical having 1-6 carbon atoms, and a R2â€”COOâ€” group where R2 is hydrogen or a linear or branched, saturated or unsaturated aliphatic hydrocarbon radical, optionally substituted by at least one hydroxylated group and having 6-22 carbon atoms, at least one X radical corresponding to R2â€”COOâ€”, ii) from 1.5 to 2.5 parts by weight of at least one polyalkoxylated fatty acid ester of formula (II) below: in which R3 is a linear or branched, saturated or unsaturated aliphatic hydrocarbon radical, optionally substituted by at least one hydroxylated group and having from 6 to 22 carbon atoms, R4 is a linear or branched alkylene group having from 1 to 10 carbon atoms, n is an integer greater than or equal to 6, and R5 is hydrogen, a linear or branched alkyl group having 1 to 10 carbon atoms, or is: R6 being a linear or branched, saturated or unsaturated aliphatic hydrocarbon radical, optionally substituted by at least one hydroxylated group and having from 6 to 22 carbon atoms,iii) from 0.5 to 2.0 parts by weight of at least one polyalkoxylated compound of general formula (III) below; in which R9 and R10 are identical or different, linear or branched alkylene groups having 1-20 carbon atoms, R7 is linear or branched alkylene having 1 to 10 carbon atoms, R8 is selected in the group consisting of hydrogen, linear or branched alkylene groups having 1 to 10 carbon atoms, and R11 being a linear or branched, saturated or unsaturated aliphatic radical, optionally substituted by hydroxylated functions and having 7-22 carbon atoms, m and p are integers varying respectively from 0-20 and from 3-10,the HLB of the emulsifying system varying from 6 to 8.
