Novel procedures are described for the production of syngas fuel intermediates from abundantly available natural gas. The novel procedures include: (a) providing a double tubular hydrogen transfer reactor having an inner tubular wall defining a heated reaction zone containing a catalyst and an outer tubular wall defining an annular zone between the tubular walls, said inner tubular wall including a hydrogen semipermeable membrane portion adapted to permit diffusion of hydrogen therethrough from the reaction zone to the annular zone while being impervious to other gases, (b) passing through said catalytic reaction zone of a feedstock comprising a mixture of methane and oxygen or a mixture of methane and carbon dioxide or a mixture of methane, carbon dioxide and oxygen, (c) continuously removing from the reaction zone at least part of the hydrogen being formed by diffusion thereof through said hydrogen semipermeable membrane into said annular zone, (d) continuously removing diffused hydrogen from said annular zone and (e) continuously removing a product mixture of carbon monoxide and hydrogen from the reaction zone.

Process for producing syngas and hydrogen from natural gas using a

An improvement in the process for the oxidative coupling of methane is provided. Typically, the reaction takes place in a reactor that includes a catalyst zone. A primary CH.sub.4 /O.sub.2 stream is fed into the entrance of the reactor and reacted at a temperature of 600.degree. C.-1000.degree. C. and a pressure of between 101 kPa and 800 kPa. The improvement comprises introducing an auxiliary oxygen stream directly into the catalyst zone and one or more points to thereby selectively increase the yield of C.sub.2+ products.
