Use of compounds revealing the efficiency of filterability additives in hydrocarbon distillates, and synergic composition containing same |
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. |

1. A method of improving the activity of filterability additives, added to a hydrocarbon distillate, the method comprising:
adding a polyacrylate to a hydrocarbon distillate containing filterability additives, the filterability additives comprising a copolymer and/or terpolymer of ethylene and of a vinyl ester of a carboxylic acid with 3 to 5 carbon atoms and of a monoalcohol comprising 1 to 10 carbon atoms, the hydrocarbon distillate being resistant to the filterability additives, wherein the polyacrylate comprises side hydrocarbon chains with 18-40 carbon atoms, and the hydrocarbon distillate has a boiling temperature comprised between 150 and 450° C., an onset crystallization temperature as measured by differential scanning calorimetry analysis, greater than or equal to −5° C., and a weight content of n-paraffins containing more than 18 carbon atoms greater than 4%, wherein the polyacrylate cooperates synergistically with the filterability additives to increase the filterability of the hydrocarbon distillate, and wherein the polyacrylate is not a polymethacrylate. |
