Abstract: A process for producing a purified hydrogen product without a pre-reformer or pre-reforming catalyst in a fired, tubular reformer where the feed stream having a carbon (i.e., C2+) molar composition greater than or equal to five percent and is mixed with a steam stream to yield a reformer feed stream with a steam-to-carbon ratio less than or equal to three. The reformer tubes contain a nickel-based catalyst without alkali promotion.

Abstract: The invention relates to a compact reactor that consists of a number of plates that are arranged like stacks and spaced some distance apart, whereby a) The plates are separated by spacers and are sealed off from one another in a gas-tight manner, b) The plates are profiled in the shape of waves, so that flow channels are formed by the wave troughs that are separated from one another by the wave crests (fins), c) The flow channels run parallel to one another and parallel to one side of the plate, d) The flow channels at least partially contain at least one catalyst material that is introduced such that gaseous and/or liquid media can flow through the flow channels, and e) The compact reactor has means (headers) for feeding at least two gaseous and/or liquid media to the flow channels or removing them therefrom. The invention also relates to the use of a compact reactor.

Abstract: A process and apparatus for converting starting materials containing hydrocarbon into a hydrogen-rich product gas is disclosed. A raw synthesis gas containing hydrogen (H2) and carbon monoxide (CO) is generated from the hydrocarbon-containing starting materials in a first process step of which at least a part undergoes a catalytically supported water-gas shift reaction to increase the percentage of hydrogen. The water-gas shift reaction is carried out at temperatures between 50 and 200° C., preferably between 60 and 150° C., and at temperatures between 1 and 10 bar, preferably between 1 and 5 bar, in a reactor in which a suitable catalyst is present.
