Frank Hershkowitz, Harry W Deckman: Pressure swing reforming. ExxonMobil Research and Engineering Company, Lawrence E Carter, Paul E Purwin, February 17, 2009: US07491250 (84 worldwide citation)

Synthesis gas is produced though a cyclic method where the first step of the cycle includes reforming a hydrocarbon feed over a catalyst to synthesis gas in a first zone of a bed and the second step reheats this first zone. A hydrocarbon feed is introduced to a bed along with CO2 and optionally stea ...
