ABSTRACT:
A process and a system are provided for producing and separating hydrogen and carbon dioxide from a hydrocarbon and steam. A hydrocarbon and steam are steam reformed and the reformed gas is shift reacted to produce a shift gas. Hydrogen is removed from the shift gas, and the hydrogen-depleted gas is reformed and shift reacted again to produce more hydrogen and carbon dioxide. The hydrogen and carbon dioxide are then separated.
