Synthesis gas produced from coal gasification can be used to produce hydrogen through water gas shift (WGS) reaction and purification procedures. A study on the Thermal Swing Sorption Enhanced Reaction that simultaneously carries out the WGS reaction and the separation of CO2 from the reaction zone by using a novel CO2 chemisorbent in a single unit operation was carried out. The new process produced a fuel-cell grade hydrogen and compressed CO2 as a by-product gas. The simultaneous removal of CO2 during WGS reaction circumvented the thermodynamic limitation and shifted equilibrium to the right resulting in the enhancement of the extent of the forward reaction. Thus, a pure hydrogen stream could be directly produced, and the process is simpler and potentially more economical than the conventional WGS. This is an abstract of a paper presented at the 2007 AIChE Annual Meeting (Salt Lake City, UT 11/4-9/2007).
