Integration of hydrogen and power generation using pressure swing reforming

摘要

The invention provides a method for generating power with a gas turbine which utilizes pressure swing reforming under conditions that facilitate CO2 capture. First a synthesis gas stream at a first pressure is produced in a pressure swing reformer. Next the synthesis gas stream is subjected to a high temperature water gas shift process to produce a CO2 containing hydrogen enriched stream from which hydrogen and CO2 each are separated. The separated hydrogen in turn is combusted with air to produce a gas turbine and the separated CO2 is easily sequestered.
