Summary: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 steam where it is reformed into synthesis gas. The synthesis gas is collected at a second zone of the bed and an oxygen-containing gas is then introduced to th is second zone of the bed and combusted with a fuel, thereby reheating the firs t zone to sufficient reforming temperatures. Additionally, a non-combusting ga s can also be introduced to the second zone to move heat from the second zone to the first zone.
