Abstract:
An additive, comprising a fatty acid and/or a derivative of a fatty acid and an amine, is used in a fuel for the purpose of increasing the efficiency of an engine combusting said fuel, in particular for the purpose of reducing the losses arising from the sliding of the pistons of an engine within their cylinders, and preferably with the result that fuel economy is improved.

Abstract:
The use of fuel compositions comprising selected hydrocarbon oils as carriers for detergents has been found to reduce deposit formation as well as prolong the functionality of fuel injectors. The selection and utilization of particularly characterized hydrocarbon oils as detergent carriers reduces intake valve deposits and combustion chamber deposits, in comparison to conventionally used carrier fluids.
Abstract:
Fuel composition and methods of making fuel compositions including 50-90 wt % pyrolysis oil, 0.1-40 wt % water, 1-30 wt % alcohol, and 0.1-4 wt % surfactant, wherein the composition is an emulsion. The pyrolysis oil may be a crude pyrolysis oil and may be produced by pyrolysis of biomass material. The pyrolysis oil and surfactant may form the continuous phase and the water and alcohol may form the dispersed phase of the emulsion. Alternatively, the water and alcohol may form the continuous phase and the pyrolysis oil and surfactant may form the dispersed phase of the emulsion.
Abstract:
The invention provides for the use of at least one oil-soluble polyoxyalkylene compound,this polyoxyalkylene compound being an oil-soluble ester, ether or ether/ester of alkoxylated polyols having at least three repeat alkoxy units derived from alkylene oxides having from 2 to 5 carbon atoms per OH group of the polyol which bears at least two aliphatic hydrocarbon radicals having from 12 to 30 carbon atoms for improving the response behavior of mineral oil cold flow improvers in middle distillates which comprise at least one ashless, nitrogen-containing detergent additive which is an oil-soluble amphiphilic compound which comprises at least one alkyl or alkenyl radical which is bonded to a polar group, the alkyl or alkenyl radical comprising from 10 to 500 carbon atoms and the polar group comprising 2 or more nitrogen atoms.
Abstract:
The invention thus provides crude oils and products which have been produced therefrom and comprise distillation residues, comprising at least one alkylphenol-aldehyde resin having a repeat structural unit of the formula where R1 is a branched alkyl or alkenyl radical which has from 10 to 40 carbon atoms and bears at least one carboxyl, carboxylate and/or ester group, R2 is hydrogen or R1 R3 is hydrogen or an alkoxy group of the formula -(A-O)m—H, A is a C2- to C4-alkylene group, m is from 1 to 100, R4 is hydrogen, a C1- to C11-alkyl radical or a carboxyl group, R5 is C1-C200-alkyl or -alkenyl, O—R6 or O—C(O)—R6, R6 is C1-C200-alkyl or -alkenyl, n is from 1 to 100 and k is 1 or 2, the use of the alkylphenol-aldehyde resin for splitting emulsions of water and crude oils or products derived therefrom, the use of the alkylphenol-aldehyde resin for improving the cold flowability of crude oils and products derived therefrom, and the use of the alkylphenol-aldehyde resin as an asphaltene dispersant in crude oils and products derived therefrom.
Abstract:
A fuel additive composition comprising (A) polyisobutyl-based nitrogen-containing dispersants with MN of the polyisobutyl group of from 650 to 1800 Dalton, (B) carrier oils substantially free of nitrogen and (C) polyisobutyl-based dispersant boosters with MN of the polyisobutyl group of from 200 to 650 Dalton, with the proviso that the difference between the MN of the polyisobutyl group of component (A) and the MN of the polyisobutyl group of component (C) is more than 100 Dalton. Said component (C) is especially useful as an intake valve clean-up booster in gasoline-operated port fuel injection internal combustion engines.
Abstract:
Petroleum products comprising biologically based carbon are provided. A biologically based surfactant is added to petroleum and an emulsion composition having lower viscosity than the petroleum is formed. The petroleum is subjected to processing and the surfactant is co-processed with the petroleum to provide petroleum products comprising biologically based carbon.
