Patent ID: 7264788

Claim:
A method for the conversion of a carbon-based fuel to a H 2 -rich product gas, comprising the steps of: (a) providing a carbon-based fuel; (b) converting said carbon-based fuel to an intermediate gas product by contacting said carbon-based fuel with at least a first conversion catalyst; (c) contacting said intermediate gas product with an absorbent material to absorb CO 2 and form a H 2 -rich gas, said absorbent material having a theoretical absorption capacity for CO 2 and having an initial surface area of at least about 5 m 2 /g and an initial pore volume of at least about 0.01 cm 3 /g; (d) extracting said H 2 -rich gas from said contacting step; (e) regenerating said absorbent; and (f) repeating said steps (a), (b), (c), (d) and (e) at least 50 times, wherein said absorbent material retains at least about 50 mol. % of said theoretical absorption capacity after each of said repeating steps.
