Making CO-Rich Syngas and High Purity H2

Overview:

This steam methane reforming method to make hydrogen and syngas with a low H2/CO ratio is unique in that the H2/CO ratio is more like that obtained from autothermal reforming. In conventional steam methane reforming methods, low H2/CO syngas ratios are obtained when the effluent is processed through additional gas separation equipment, e.g. membrane or PSA. The Figures below show the schematic of the process and the CO2 removal system that is the source of CO2 feed into the primary and secondary reformers.

Benefits:

  • Simultaneous production of hydrogen and syngas with H2/CO ratio <2.5
