Hydrogen generation system with methanation unit

摘要

A hydrogen generation system includes a hydrogen generator reacting a steam/methane mixture. Calcium oxide particles in the hydrogen generator absorb a substantial reacted portion of carbon dioxide from the reacted steam/methane mixture. The hydrogen generator discharges a hydrogen/COx gas volume. A methanation unit subsequently converts substantially all of the COx portion of the hydrogen/COx gas volume to methane gas.
