Abstract (en)

[origin: WO0162662A1] The invention concerns a method for producing a gas mixture containing hydrogen and carbon monoxide, and optionally nitrogen, from at least a hydrocarbon such as methane, propane, butane or LPG or natural gas, which consists in performing a partial catalytic oxidation (1) of one or several hydrocarbons, at a temperature of 500 DEG C, at a pressure of 3 to 20 bars, in the presence of oxygen or a gas containing oxygen, such as air, to produce hydrogen and carbon monoxide; then in recuperating the gas mixture which can subsequently be purified or separated, by pressure swing adsorption, temperature swing adsorption of by permeation (3), to produce hydrogen having a purity of at least 80 % and a residue gas capable of supplying a cogeneration unit. In another embodiment, the gas mixture can subsequently be purified of its water vapour impurities and carbon dioxide to obtain a thermal treatment atmosphere containing hydrogen, carbon monoxide and nitrogen.
