Abstract
In a fluid catalytic cracking (FCC) process coked catalyst is partially regenerated by contacting with high temperature steam in the absence of oxygen. About 10 to 30% of the coke is converted to a steam reformed gas comprising hydrogen, methane and carbon dioxide. The off-gas may be subjected to cryogenic separation to yield a hydrogen-rich gas.
