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 |
20110107660 | APPLICATIONS OF HYDROXY FATTYACID DERIVATIVES AS FUELS AND FUEL ADDITIVES - The present invention is related to the use of hydroxyalkanoic acid derivatives as a fuel additive. In particular, the present invention provides the use of lower alkyl esters and/or salts of hydroxyalkanoic acid as biofuels and/or fuel additives. The present invention also provides a fuel composition including at least one fuel and lower alkyl esters and/or salts of hydroxyalkanoic acid. | 05-12-2011 |
20130167431 | NON-AQUEOUS LUBRICANT AND FUEL COMPOSITIONS COMPRISING FATTY ACID ESTERS OF HYDROXY-CARBOXYLIC ACIDS, AND USES THEREOF - The use as an anti-wear additive and/or friction modifier in a non-aqueous lubricant composition and/or in a fuel composition of at least one long chain fatty acid ester of a hydroxy carboxylic acid in which the long chain fatty acid has at least 4 carbon atoms and the ester is an oil-soluble ester of a mono- or poly-hydroxy carboxylic acid having 1 to 4 groups which are independently carboxylic acid groups or lower hydrocarbyl esters thereof and in which, when the hydroxy carboxylic acid is a mono-hydroxy carboxylic acid, the ester has a long chain fatty acid ester moiety of the hydroxy group of the hydroxy carboxylic acid and, when the hydroxy carboxylic acid is a poly-hydroxy carboxylic acid, the ester has independently long chain fatty acid ester moieties of one or two of the hydroxy groups of the poly-hydroxy carboxylic acid. Also, a non-aqueous lubricant composition and a fuel composition for an internal combustion engine which comprises at least one of said long chain fatty acid esters. | 07-04-2013 |
20140047762 | FUEL ADDITIVE AND METHOD FOR USE - Methods of making fuel additives and fuel additive formulations are presented that include degummed lipid acid or lipid ester; a bean oil and/or seed oil; a pour point depressant; and glycerol monooleate or glycerol monostearate. The fuel additives can be added to any fuel and result in advantages such as an increased shelf life. | 02-20-2014 |
20140115954 | METHOD FOR MANUFACTURING AN AVIATION FUEL OIL COMPOSITION - To provide an aviation fuel oil composition which has excellent life cycle characteristics and achieves excellent specific fuel consumption. The aviation fuel oil composition according to the present invention includes: a first base which is a fraction having a boiling range of 140 to 280° C. obtained through a step of hydrotreating a first feedstock containing a sulfur-containing hydrocarbon compound and an oxygen-containing hydrocarbon compound derived from an animal or vegetable oil and fat or a second feedstock which is an oil blend of the first feedstock and a petroleum-based base obtained by refining a crude oil; and a second base which is a fraction having a boiling range of 140 to 280° C. obtained from a heavy oil cracking apparatus. | 05-01-2014 |
20140215904 | COMPOSITIONS COMPRISING AND METHODS FOR PRODUCING BETA-HYDROXY FATTY ACID ESTERS - Disclosed are fatty ester compositions comprising beta-hydroxy fatty esters, as well as methods for producing beta-hydroxy fatty esters, and recombinant microorganisms useful in methods of producing beta-hydroxy fatty esters | 08-07-2014 |
