Title:
FUEL OIL COMPOSITION
Document Type and Number:
Japanese Patent JP3903559
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a fuel oil composition capable of improving the low- temperature fluidity of various fuel oils such as kerosene, light oil or fuel oil A and maintaining the high fluidity even in the winter season or in a cold district.
SOLUTION: This fuel oil composition is obtained by compounding a petroleum middle distillate oil with the following various components: (A) 0.1-5 mass% one or more kinds of residual carbon imparting agents selected from atmospheric residual oils, vacuum residual oils, desulfurization bottom residues, slurry oils and extract oils, (B) the first fluidity improver which is an ethylene- vinyl carboxylate copolymer and (C) the second fluidity improver that is a graft addition product of an unsaturated dicarboxylic acid ester to an ethylene- vinyl acetate copolymer. The total amount of the components B and C is 0.005-0.5 mass%, preferably 0.005-0.1 mass% and the ratio of the components B:C is preferably (50-70):(30-50) expressed in terms of mass%.
