Two component flow improver additive for middle distillate fuel oils

摘要

Distillate fuels, particularly those having a relatively high final boiling point, are significantly improved in their flow and filterability properties utilizing a two component additive consisting of 25 to 95 wt. % preferably 50 to 90 wt. % of C30-C300 oil-soluble nitrogen compound being an amide or amine salt of an aromatic or cycloaliphatic carboxylic acid and 75 to 5 wt. % preferably 10 to 50 wt. % of a certain category of ethylene-vinyl acetate copolymers.
