Process for the production of a mixture comprising hydrogen and carbon monoxide

摘要

Combustion of the light hydrocarbon takes place in a zone comprising porous material during which the combustion gases restore their enthalpy to the porous medium and leave the reactor at the adiabatic temperature. Production of a gaseous mixture containing hydrogen and carbon monoxide, by the partial oxidation of a light hydrocarbon by an oxygenated medium, the process operating autothermically. The heat released by the oxidation is recovered to maintain the endothermic reaction produced between the non-oxidized hydrocarbon fraction and CO2 and water vapour. The gaseous reaction mixture is passed through a porous pre-heated zone enabling heating by thermal exchange to a temperature threshold sufficient to initiate the combustion reactions ; application of external heat is thus superfluous when functioning permanently.
