USE OF EFFICIENCY REVEAL COMPOUNDS OF FILTERABILITY ADDITIVES IN HYDROCARBON DISTILLATES, AND SYNERGIC COMPOSITION COMPRISING THEM

摘要

The invention relates to the use, in a hydrocarbon distillate with a boiling temperature of between 150 and 450°C and a crystallization onset temperature as measured by Differential Calorimetric Analysis of greater than or equal to -50°C, preferably of -5°C to +10°C, of a homopolymer obtained from an olefinic ester of carboxylic acid of 3 to 12 carbon atoms and from a fatty alcohol containing a chain of more than 16 carbon atoms and optionally an olefinic double bond, as a compound for revealing the efficiency of filterability additives based on copolymer and/or terpolymers of ethylene and of vinyl ester of a carboxylic acid of 3 to 12 carbon atoms, and of a monoalcohol containing 1 to 10 carbon atoms. The invention is also directed to an additive composition comprising a conventional hydrocarbon filterability additive in combination with an efficiency reveal additive, and also to the combustion fuels, motor fuel and oil fuel that comprise these additive combinations.
