Process for the preparation of hydrogen by reacting a feed gas comprising methane and carbon monoxide with steam in the presence of a steam reforming catalyst at a pressure of at least 15 bara in the heated zone of a steam reformer to obtain a raw hydrogen containing product stream, wherein (a) the feed gas is mixed with the steam before entering the steam reformer resulting in a reaction mixture of the feed gas and steam having a temperature below 540° C.; and (b) the reaction mixture obtained in step (a) is fed into the heated zone of the steam reformer where it is first contacted with an inert material before it is contacted with the steam reforming catalyst.

A process for producing syngas that uses the syngas product from an oxygen-fired reformer to provide all necessary heating duties, which eliminates the need for a fired heater. Without the flue gas stream leaving a fired heater, all of the carbon dioxide produced by the reforming process is concentrated in the high-pressure syngas stream, allowing essentially complete carbon dioxide capture.

The disclosure relates to methods, systems, and apparatus arranged and designed for converting non-methane hydrocarbon gases into multiple product gas streams including a predominately hydrogen gas stream and a predominately methane gas steam. Hydrocarbon gas streams are reformed, cracked, or converted into a synthesis gas stream and methane gas stream by receiving a volume of flare gas or other hydrocarbon liquid or gas feed, where the volume of hydrocarbon feed includes a volume of methane and a volume of nonmethane hydrocarbons. The hydrogen contained in the syngas may be separated into a pure hydrogen gas stream. A corresponding gas conversion system can include a super heater to provide a hydrocarbon feed/steam mixture, a heavy hydrocarbon reactor for synthesis gas formation, and a hydrogen separator to recover the hydrogen portion of the synthesis gas.
