Abstract
Methods of using sorbents to enhance the production of hydrogen from fuel, and related systems, are generally described. In some embodiments, the production of hydrogen from the fuel involves a reforming reaction and/or a gasification reaction combined with a water-gas shift reaction.
Claims20
A system, comprising:
- a reactor configured to react carbon monoxide (CO) in a water-gas shift reaction (WGSR) that generates (i) hydrogen and (ii) carbon dioxide (CO2), and
- a separator in fluid communication with said reactor, wherein said separator comprises a molten sorbent comprising a salt in molten form, wherein said molten sorbent is configured to capture at least a portion of said CO2, thereby obtaining captured CO2.
A method, comprising:
- directing carbon monoxide (CO) into a reactor;
- in said reactor, reacting said CO in a water gas shift reaction (WGSR) that generates (i) hydrogen and (ii) carbon dioxide (CO2);
- and
- directing a stream comprising said CO2 from said reactor to a separator in fluid communication with said reactor, wherein said separator comprises a molten sorbent comprising a salt in molten form that captures at least a portion of said CO2, thereby obtaining captured CO2.
