Abstract
This invention relates to a fuel composition, comprising: (A) a normally liquid fuel; and (B) a cold flow improving amount of (i) a metathesized natural oil; (ii) a metathesized natural oil derivative; or (iii) a mixture of (i) and (ii). The invention also relates to metathesized derivatives formed by the reaction of a metathesized natural oil with a nucleophile, oxidizer, aromatic compound, enophilic acid reagent, or a mixture of two or more thereof.
Claims54
A fuel composition, comprising:
- (A) a normally liquid fuel, the normally liquid fuel comprising a middle distillate fuel;
- and
- (B) a cold flow improving amount of (i) a metathesized natural oil, the metathesized natural oil comprising a metathesis oligomer and/or metathesis polymer;
- (ii) a metathesized natural oil derivative;
- or (iii) a mixture of (i) and (ii) for lowering the cloud point, pour point and/or cold filter plugging point of the normally liquid fuel.
