    Abstract: The present invention relates to a process for producing a hydrogen containing gas mixture comprising the following steps: (i) providing a preheated mixture comprising a fossil fuel, preferably methane, and steam, (ii) conducting an adiabatic reaction between the fossil fuel and the steam, in the presence of a catalyst, wherein a first reaction product mixture is formed comprising methane, hydrogen and carbon dioxide, and (iii) conducting an oxygen-assisted reforming reaction in the presence of a catalyst between said first reaction product mixture and an oxygen comprising stream, wherein the oxygen comprising stream comprises at least 40 vol% oxygen, forming a second reaction product mixture comprising hydrogen and carbon monoxide. The invention also relates to a system suitable for hydrogen production from a hydrocarbon feed according to the present invention.

    Abstract: The present invention relates to a method for hydrogen production and to a method of hydrogen and/or carbon dioxide production from syngas. The method comprises the steps of: (i) providing a gas stream comprising hydrogen and carbon monoxide, (ii) separating at least part of hydrogen from the stream yielding a hydrogen-depleted stream, (iii) subjecting the hydrogen- depleted stream to a water-gas shift reaction, and (iv) separating hydrogen from the stream resulting from step (iii). The method according to the invention improves the conversion of carbon monoxide in the water gas shift reaction and allows to increase the hydrogen production by 10-15% and to increase the overall energy efficiency of the system by 5-7%. The invention further relates to a plant for hydrogen and/or carbon dioxide production suitable for the method of the invention.
