Abstract:
The invention relates to a method for the parallel production of hydrogen (3) and of one or a plurality of carbon-containing products (8). In the method, hydrocarbons (2) are introduced into a reaction chamber (R) and are thermally decomposed into carbon and hydrogen in the presence of a carbon-rich granulated material (W). The invention is characterised in that at least a portion of the thermal energy necessary for the decomposition of the hydrocarbons is introduced into the reaction chamber (R) via a gaseous heat transfer medium.

Abstract:
The present invention relates to a method for operating a descending moving bed reactor with flowable granular material, said method comprising the steps of (i) Filling a upper lock-hopper with granular material and/or emptying a lower lock-hopper, (ii) Purging the lock-hoppers with purging gas, (iii) Filling the reaction chamber comprising a descending moving bed from the upper lock-hopper and/or emptying the reaction chamber into the lower lock-hopper, wherein the pressure equalization between the reaction chamber and lock-hopper is achieved with product gas, (iv) optionally Relieving the lock-hoppers and conveying the product gas flow into the product line and (v) Purging the lock-hoppers with purging gas.
Abstract:
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.
Abstract:
The invention relates to a method for performing endothermic process, characterized in that the annual average total energy required for the endothermic process originates from at least two different energy sources. One of the energy sources is an electrical energy source, the power of which varies between 0 and 100% of the required total power, and three different energy modes individually can provide the total required power for the endothermic process: (i) exclusively electrical energy, (ii) a mixture of electrical energy and at least one additional non-energy source, or (iii) exclusively non-electrical energy. The transition time in which the change from one energy mode to another energy mode is completed 30 minutes at most.
Abstract:
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).
Abstract:
The present invention relates to a gas-tight multilayer composite tube with a heat transfer coefficient of > 500 W/m2/K, which in its structure has, as an inner layer over the cross section of the wall of the composite tube, a non-porous monolithic oxide ceramic, which is enclosed by an outer layer of oxidic fibre-composite ceramic, this outer layer having an open porosity of 5%
Abstract:
Procedimiento para el aprovechamiento de un gas de subproducto, un gas acompañante y/o un biogás que contienen hidrocarburos y que contienen dióxido de carbono, caracterizado porque el gas de subproducto, el gas acompañante y/o el biogás que contienen hidrocarburos y que contienen dióxido de carbono se introducen en un espacio de reacción y la mezcla de múltiples componentes contenida en el gas de subproducto, el gas acompañante y/o el biogás se convierte en una zona de alta temperatura a temperaturas de entre 1100 y 1400 ºC y en presencia de un soporte en una mezcla gaseosa de producto que está constituida en más del 95 % por CO, CO2, H2, H2O, CH4 y N2, en donde se conduce el soporte como lecho móvil por el espacio de reacción y se conduce la mezcla gaseosa de gas de subproducto, gas acompañante y/o biogás en contracorriente con respecto al soporte y se conduce el gas de síntesis caliente formado en la zona de alta temperatura posteriormente en contracorriente por el lecho móvil y se enfría en intercambio de calor directo con éste, ascendiendo la velocidad de flujo de la mezcla gaseosa de gas de subproducto, gas acompañante y/o biogás en la zona de reacción a menos de 20 m/s y enfriándose el gas de síntesis formado en la zona de alta temperatura con > 200 K/s.
