摘要： 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.

摘要： A plant and process for producing a hydrogen rich gas and improved carbon capture are provided, said process comprising the steps of: reforming a hydrocarbon feed by optional prereforming, autothermal reforming (ATR), yet no primary reforming, thereby obtaining a synthesis gas; shifting said synthesis gas in a shift section including a high temperature shift step; removal of CO2 upstream hydrogen purification unit, thereby producing a hydrogen rich stream and an off-gas stream, and where at least part of the off-gas stream is recycled to the process, thus to the ATR and optional prereforming, and/or to the shift section.
