摘要:
Packaged detergent composition comprising a container that at least partly disintegrates in an aqueous environment, the detergent composition comprising at least one liquid and at least one solid substantially insoluble in the liquid and preferably having a size sufficient to be retained by a 2.5 mm mesh wherein the at least one solid has a density lower than the density of the liquid
摘要:
The invention relates to a process for mineral oil production by means of Winsor Type III microemulsion flooding, in which an aqueous surfactant formulation comprising at least one ionic surfactant of the general formula R1—O—(CH2C(CH3)HO)m(CH2CH2O)n—XY−M+ is injected through injection boreholes into a mineral oil deposit, and crude oil is withdrawn from the deposit through production boreholes. The invention further relates to ionic surfactants of the general formula.
摘要:
The use of a surfactant mixture comprising at least one surfactant having a hydrocarbon radical composed of from 12 to 30 carbon atoms and at least one cosurfactant having a branched hydrocarbon radical composed of from 6 to 11 carbon atoms for tertiary mineral oil extraction.
摘要:
Water-soluble, hydrophobically associating copolymers which comprise new types of hydrophobically associating monomers. The monomers comprise an ethylenically unsaturated group and a polyether group with block structure comprising a hydrophilic polyalkylene oxide block which consists essentially of ethylene oxide groups, and a terminal, hydrophobic polyalkylene oxide block which consists of alkylene oxides with at least 4, preferably at least 5 carbon atoms.
摘要:
Process for the production of synthesis gas (3), in which methane and carbon dioxide (2) are introduced into a reaction space (R) and reacted in the presence of a solid (W) at elevated temperatures to give hydrogen and carbon monoxide. Methane and carbon dioxide are passed through a carbon-containing granular material (W) and reacted in a high-temperature zone (H).
摘要:
The invention relates to a process for parallel preparation of hydrogen and one or more carbonaceous products, in which hydrocarbons are introduced into a reaction space (R) and decomposed thermally to carbon and hydrogen in the presence of carbon-rich pellets (W). It is a feature of the invention that at least a portion of the thermal energy required for the hydrocarbon decomposition is introduced into the reaction space (R) by means of a gaseous heat carrier.
摘要:
The present invention relates to processes for tertiary mineral oil production with the aid of a surfactant mixture and to the use of a surfactant mixture for tertiary mineral oil production by means of Winsor type III microemulsion flooding, by injecting a surfactant mixture through at least one aqueous injection borehole into a mineral oil deposit, and withdrawing crude oil from the deposit through at least one production borehole, wherein the surfactant mixture, for the purpose of lowering the interfacial tension between oil and water to
