Abstract (en)
An additive composition for improving the low temperature flow properties of a wax-containing petroleum distillate fuel comprises: A. an amide and/or amine salt of a carboxylic acid and/or anhydride; B. an ethylene polymer and/or copolymer; C. a condensation product of a halogenated paraffin or an olefin with an aromatic compound; D. an alkylated diphenyl ether. Examples of each component are (A) tetraalkyl ammonium phthalamate, (B) ethylene vinyl acetate, (C) a wax-naphthalene condensate, and (D) diphenyl ether alkylated with a dimer of a C24 alpha olefin. Preferred treat rates are from 0.01 to 0.15 wt % of (A); 0.005 to 0.5 wt % of each of (B) and (D); and 0.002 to 0.1 wt % of (C), each based on the fuel, which is preferably one having a boiling range within the limits 120 DEG C and 450 DEG C.
