Abstract
According to the present invention, hydrogen/carbon monoxide synthesis gas (also called syngas) is produced by injection of a second reactant stream into a hydrocarbon reformer at a location between the entry and discharge ends of the reformer. The second reactant stream can contain: carbon dioxide; a mixture of carbon dioxide and hydrocarbon; a mixture of hydrocarbon and steam, a mixture of carbon dioxide and steam; or a mixture of carbon dioxide with hydrocarbon and steam. All or part of the mixtures containing hydrocarbon and steam can be prereformed hydrocarbon in steam.
