Abstract
A splash-blendable, solubilized diesel fuel composition includes a diesel fuel, ethanol, a stabilizing additive and, optionally, an alkyl ester of a fatty acid and/or a co-solvent. The stabilizing additive is either a mixture of fatty acid alcohols, a polymeric material, or a combination of the mixture and the polymeric material.
Claims22
A fuel composition comprising a solution of:
- (a) diesel fuel;
- (b) ethanol;
- (c) a stabilizing, additive selected from the group consisting of:
- (i) a mixture comprising two different ethoxylated fatty alcohols each having a hydrocarbon chain length of about 9 to about 13 carbon atoms present in a molar ratio with respect to the other of about 1:3 to about 3:1, inclusive;
- 0 volume percent (vol. %) to about 10 vol. %, inclusive, based on the volume of the mixture, of a cetane booster;
- and 0 vol. % to less than about 5 vol. % of a demulsifier based on the volume of the mixture;
- and,
- (ii) the reaction product of (1) a mixture of an ethoxylated alcohol and an amide, said ethoxylated alcohol comprising at least about 75 weight percent of at least one linear straight chain alcohol having a hydrocarbon chain length of about 9 to about 15 carbon atoms, and said amide being a substantially equimolar reaction product of an alcohol amine and an alkyl ester of a fatty acid;
- and, (2) an ethoxylated fatty acid or derivative thereof having a hydrocarbon chain length of about 9 to about 15 carbon atoms;
- (d) optionally, an alkyl ester of a fatty acid;
- and,
- (e) optionally, a cosolvent.
