Abstract:
1. A middle distillate comprising the middle distillate having a blank cloud point and from 1 to 2000 ppm of an additive for improving the cold flow performance and improving paraffin dispersancy of the middle distillate for a storage temperature below said blank cloud point, said additive comprising I) at least one paraffin dispersant which is a derivative of a fatty amine, selected from the group consisting of II) at least one poly(styrene-b-butadiene-b-styrene) block copolymer having a molecular weight between 3000 and 110 000 g/mol, and III) one or more copolymer of ethylene and an olefinically unsaturated compound, wherein a ratio of component I to component II is between 1:10 and 1:0.1 and wherein after 16 hours at said storage temperature a resulting 20% by volume bottom oil phase having a bottom cloud point has a deviation between the blank cloud point and the bottom cloud point of less than 5 degrees C.
