Patent ID: 7713316

Claim:
A fuel oil having improved filterability consisting of A) a proportion of mineral oil middle distillate or a proportion of mineral oil distillate and a mixture of fatty acid alkyl esters, said fuel oil having a sulfur content of at most 350 ppm, a total aromatics content of at most 22% by weight of said mineral oil middle distillate, and B) a cold flow additive consisting of a proportion of at least one copolymer of ethylene and vinyl esters, said copolymer consisting of comonomers a) bivalent structural units derived from ethylene of the formula 1 —CH 2 —CH 2 — (1) b) from 5 to 12 mol % of bivalent structural units of the formula 2 where R 1 is a saturated, tertiary-branched C 5 -C 18 -alkyl, and c) from 4 to 13 mol % of bivalent structural units of the formula 3 wherein a sum of molar proportion of comonomers b) and c) is between 12 and 16 mol %, and, d) up to 5 mol % of a further comonomer selected from the group consisting of olefins having from 3 to 18 carbon atoms, esters of acrylic acid or methacrylic acid with C 1 -C 18 -alcohols, C 1 -C 18 -alkyl vinyl ethers, and mixtures thereof, and C) at least one compound selected from the group consisting of a polar nitrogen compound, an alkylphenol-aldehyde resin, a comb polymer, a polyoxyalkylene derivative, and mixtures thereof, and D) at least one additive selected from the group consisting of a dewaxing assistant, a corrosion inhibitor, an antioxidant, a lubricity additive, a dehazer, a conductivity improver, a cetane number improver, a sludge inhibitor, and mixtures thereof.
