Abstract
A fuel composition including a fuel oil obtained from the distillation of a pyrolysis oil having a boiling point distribution within the gasoline range and, as an additive, one or more of: (a) an antioxidant; and (b) a stabilising additive selected from (x) alkoxylated amine compounds; (y) aldehyde-alkylphenol copolymers; (z) acylated nitrogen compounds; and mixtures thereof. Also disclosed are a method and use for improving the stability of a fuel composition including a fuel oil obtained from the distillation of a pyrolysis oil, having a boiling point distribution within the gasoline range, which involve adding to the composition one or more additives selected from (a) and (b).
Claims15
A fuel composition comprising a fuel oil obtained from the distillation of a pyrolysis oil having a boiling point distribution within the gasoline range and, as additives:
- (a) a phenolic antioxidant;
- and
- (b) a stabilising additive (z) an acylated nitrogen compound which is the reaction product of a polyisobutene-substituted succinic acid or succinic anhydride and a polyethylene polyamine.
