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.

Method for the parallel production of hydrogen and carbon-containing products

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.

Use of surfactant mixtures for tertiary mineral oil extraction

Water-soluble, hydrophobically associating copolymer comprising a monoethylenically unsaturated, water-soluble, surface-active monomer (a), and a monoethylenically unsaturated, hydrophilic monomer (b) different from monomer (a). The copolymer is prepared in the presence of a nonpolymerizable surfactant and has marked thickening properties in aqueous systems.

Water-soluble, hydrophobic associating copolymers

The use of a nondendrimeric hyperbranched polyester and/or a polyesteramide which comprise alkenyl-substituted succinic acid units as a demulsifier for splitting oil-water emulsions. The succinic acid is substituted by at least one alkenyl group containing from 16 to 20 carbon atoms. Particular emulsions suitable for splitting are crude oil emulsions. Also, a nondendrimeric hyperbranched polyester or a polyesteramide which comprises alkenyl-substituted succinic acid units, the alkenyl group having from 16 to 20 carbon atoms. In addition to the alkenyl-substituted succinic acid units, the nondendrimeric hyperbranched polyester contains, as further units, at least trifunctional alcohols having been alkoxylated with an average of from 3 to 12 ethylene oxide units.

Use of hyperbranched polyesters and/or polyester amides for separating oil-in-water emulsions

A nondendrimeric hyperbranched polyester and/or polyesteramide which comprise alkenyl-substituted succinic acid units as demulsifiers for splitting oil-water emulsions, especially crude oil emulsions. In particular, the succinic acid is substituted with alkenyl groups containing 16 to 20 carbon atoms. Also, nondendrimeric hyperbranched polyesters or polyesteramides which comprise alkenyl-substituted succinic acid units, wherein the alkenyl group has from 16 to 20 carbon atoms. In addition to the alkenyl-substituted succinic acid units, the nondendrimeric hyperbranched polyester contains, as further units, at least trifunctional alcohols having been alkoxylated with an average of from 3 to 12 ethylene oxide units.

Process for the production of synthesis gas (), in which methane and carbon dioxide () 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).
