| 20080295394 | Cetane-Improving Component for Diesel Fuels and Diesel Fuels Containing it - Cetane improver for diesel fuels, characterized in that it comprises at least one ester of stearic acid, selected from the esters of linear or branched monoalcohols containing 1 to 6 carbon atoms: a) added in the pure state to a mixture of at least one vegetable or animal oil ester in crude or partially hydrogenated form b) or else included in a mixture of esters of one or more vegetable and/or animal oils, in crude or partially hydrogenated form, the mixtures of saturated or unsaturated esters being such that the ratio by mass of the amount of stearic ester(s) to the total sum of the amounts of unsaturated esters present in the vegetable or animal oil esters varies from 1% to 12%, and the unsaturated fatty acid esters being esters of mono or polyunsaturated acids containing at least 18 carbon atoms with monoalcohols. | 12-04-2008 |
| 20100058653 | USE OF COMPOUNDS REVEALING THE EFFICIENCY OF FILTERABILITY ADDITIVES IN HYDROCARBON DISTILLATES, AND SYNERGIC COMPOSITION CONTAINING SAME - 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. | 03-11-2010 |
| 20100251606 | GRAFT MODIFIED VINYL ESTER AND ETHYLENE POLYMERS, PREPARATION METHOD THEREOF AND USE OF SAME AS ADDITIVES THAT IMPROVE THE COLD PROPERTIES OF LIQUID HYDROCARBONS - This disclosure concerns the synthesis and use of novel polymers based on ethylene and vinyl esters, modified by conjugation to improve their solubility in liquid hydrocarbons, as double-purpose additives to improve the filterability and flow of liquid hydrocarbons at low temperatures, in particular for middle distillates derived from the distillation of petroleum and crude oil. | 10-07-2010 |
| 20100275508 | BIFUNCTIONAL ADDITIVES FOR LIQUID HYDROCARBONS OBTAINED BY GRAFTING STARTING WITH COPOLYMERS OF ETHYLENE AND/OR PROPYLENE AND VINYL ESTER - The disclosure relates to the synthesis and the use of copolymers based on ethylene and/or of propylene and of vinyl ester(s) modified by grafting, effective for improving both the resistance to cold and the lubricity of liquid hydrocarbons in particular the middle distillates originating from the distillation of petroleum and crude oils, in particular those with a low sulphur content and relates to a copolymer including:
