    Abstract: A process for producing synthesis gas, the process including the steps of: a) in a reforming reactor, reacting a hydrocarbon feed stream together with an oxidant gas stream, thereby producing a first synthesis gas stream; b) providing a heated CO2 rich gas stream to an adiabatic post converter including a second catalyst active for catalyzing steam methane reforming, methanation and reverse water gas shift reactions; and c) in the adiabatic reforming post converter, letting at least a part of the first synthesis gas stream and the heated CO2 rich gas stream undergo steam methane reforming, methanation and reverse water gas shift reactions to thereby provide a product gas stream, the product gas stream being a synthesis gas stream. Also, a system for producing synthesis gas.

    Abstract: The invention relates to a chemical reactor and reformer tubes for reforming a first feed stream comprising a hydrocarbon gas and steam. The chemical reactor comprises a shell with a heat source and one or more reformer tubes. The reformer tube is arranged to house catalyst material and is arranged to being heated by the heat source. The reformer tube comprises a first inlet for feeding said first feed stream into a first reforming reaction zone of the reformer tube, and a feed conduct arranged to allow a second feed stream into a second reforming reaction zone of the reformer tube. The second reforming reaction zone is positioned downstream of the first reforming reaction zone. The feed conduct is configured so that the second feed stream is only in contact with catalyst material in the second reforming reaction zone. The invention also relates to a process of producing CO rich synthesis gas at low S/C conditions.
