The invention relates to a method and apparatus for producing a product gas from a feed comprising at least carbon dioxide, hydrogen and hydrocarbons. The feed is supplied to a reactor comprising a catalyst, the catalyst is heated electrically, the feed is supplied through the catalyst and a reaction is performed at least between carbon dioxide (CO.sub.2) and hydrogen (H.sub.2) in the presence of the catalyst in the reactor, and the product gas comprising at least carbon monoxide (CO) and hydrogen (H.sub.2) is formed in the reactor. Further, the invention relates to the use of the method.

A pyrolysis reactor (12) and method for the pyrolysis of hydrocarbon gases (e.g., methane) utilizes a pyrolysis reactor (12) having a unique burner assembly (44) and pyrolysis feed assembly (56) that creates an inwardly spiraling fluid flow pattern of the feed gases to form a swirling gas mixture that passes through a burner conduit (46) with a constricted neck portion or nozzle (52). At least a portion of the swirling gas mixture forms a thin, annular mixed gas flow layer immediately adjacent to the burner conduit (46). A portion of the swirling gas mixture is combusted as the swirling gas mixture passes through the burner conduit (46) and a portion of combustion products circulates in the burner assembly (44). This provides conditions suitable for pyrolysis of hydrocarbons or light alkane gas, such as methane or natural gas.

A method and apparatus for reforming carbonaceous material into syngas containing hydrogen and CO gases is disclosed. In one embodiment, a hydrogen rich torch reactor is provided for defining a reaction zone proximate to torch flame. One input of the reactor receives input material to be processed.
