Production of synthesis gas

The state-of-the-art for the production of synthesis gas from the steam reforming of methane is reviewed and discussed. Particular attention is given to the design of the tubular reformer and carbon formation on the nickel catalyst. Improvements in syngas technology are discussed, including: CO₂ reforming, autothermal reforming and heat exchange reforming, and the energy efficiencies of direct and indirect methane conversion are compared and contrasted.
