PROCESS FOR THE PREPARATION OF HYDROGEN-CONTAINING GAS FROM HYDROCARBONS AND STEAM AND/OR CO2

摘要

Process for the preparation of hydrogen-containing gas from hydrocarbons (e.g. methane) and steam and/or CO2 wherein the hydrocarbons and the steam and/or the CO2 are continuously converted in at least one reaction zone at elevated temperature and pressure into H2 and CO by continuously contacting the reactants with at least one fluidized bed of heated solid particles, which are then led continuously to a heating zone where they are continuously heated in a fluidized state by combustion of a part of the obtained H2 and/or of at least a part of the obtained CO with oxygen-containing gas, and which are finally led continuously back to the reaction zone(s) where they are again contacted with the reactants.
