Abstract: A reactor for carrying out an endothermic reaction, in particular a high-temperature reaction, in which a product gas is obtained from a feed gas, wherein: the reactor surrounds a reactor interior; the reactor is configured to provide a reactor bed in a reaction zone of the reactor interior, which reactor bed comprises a large number of solid material particles; the reactor is also configured to guide the feed gas into the reaction zone; in order to heat the feed gas, the reactor is designed to heat the solid material particles in the reaction zone such that, by transferring heat from the solid material particles to the feed gas, the feed gas in the reaction zone can be heated to a reaction temperature in order to participate as a starting product in the endothermic reaction for producing the product gas.

Abstract: The invention relates to a reactor comprising a moving bed of solid particles that move in the direction of gravitation, and to a method for heating a reactor that comprises a moving bed, for the purpose of pyrolysis reactions.

Abstract: The invention relates to a process for producing hydrogen, carbon monoxide and a carbon-containing product in at least one reaction apparatus, wherein the at least one reaction apparatus comprises a bed of carbon-containing material and is characterized in that the bed of carbon-containing material in the at least one reaction apparatus is alternately heated to a temperature of >800° C. and, no later than upon reaching a temperature of 1800° C., cooled to a maximum of 800° C., wherein hydrogen and carbon monoxide are produced during the heating phase and carbon and hydrogen are produced during the cooling phase.

Abstract: A method for producing synthesis gas may involve introducing a hydrocarbon-containing coke-oven gas and a carbon dioxide-containing converter gas into a first reaction zone where hydrogen present in the hydrocarbon-containing coke-oven gas reacts at least partly with carbon dioxide to form water, which reacts thermally with hydrocarbon to form synthesis gas containing carbon monoxide and hydrogen. The method may further involve introducing an oxygen-containing gas in a second reaction zone, and using the oxygen-containing gas and some hydrogen from the first reaction zone to produce thermal energy. Still further, the method may involve supplying the thermal energy produced in the second reaction zone to the first reaction zone.

Abstract: The invention relates to a method for producing syngas in combined operation with a metallurgical plant which comprises at least one blast furnace for producing crude iron, a converter steel mill and a coke-oven plant. Part of the blast-furnace top gas that is produced in the production of crude iron and/or part of the converter gas that occurs in the converter steel mill and/or part of the coke-oven gas that is produced in the coke-oven plant are mixed. By choosing the gas streams that are brought together to form a mixed gas and/or by changing the mixing ratios of the gas streams that are brought together, at least two streams of useful gas are produced, differing with regard to their composition and respectively prepared to form streams of syngas.

Abstract: Supports having a catalytic coating comprising at least one porous and cavity-containing catalyst layer are described, cavities being irregular spaces having dimensions greater than 5 ?m in at least two dimensions or having cross-sectional areas of at least 10 ?m2. The catalytic coatings are distinguished by a high adhesive strength and can preferably be used in microreactors.
