ADDITIVES IMPROVING LOW-TEMPERATURE PROPERTIES OF FUEL DISTILLATES AND MIXTURES OF AFTER-DISTILLATION INTERMEDIATE FRACTIONS HAVING IMPROVED LOW-TEMPERATURE FLOW PROPERTIES

摘要

The low temperature properties of a distillate petroleum fuel oil boiling in the range 120 DEG C to 500 DEG C and having a final boiling point above 370 DEG C, are improved particularly the lowering of the cloud point by the addition of a polymer or copolymer having at least 25 wt.% of n-alkyl groups of average number of carbon atoms from 14 to 18 with no more than 10 wt.% containing less than 14 carbon atoms and no more than 10 wt.% containing more than 14 carbon atoms
