Evaluation of Sorption-Enhanced Water Gas Shift Reaction
Water-gas shift reaction, reacting water with CO is used to change the CO/H2 ratio for chemical production and for producing pure hydrogen. Water-gas shift (WGS) reaction in combination with CO2 absorption will have many applications in fuel cell and coal/biomass processing systems and will play a significant role in reducing CO2 from fossil fuel power generating systems such as IGCC by increasing system efficiencies and reducing fuel consumption. The exothermic and reversible WGS reaction, CO(g) + H2O(g) <=> CO2 (g) + H2 (g) ΔH298 = - 41 kJ/mol (1), is not thermodynamically favorable at higher temperatures and for obtaining a higher conversion excess steam plus several reactors are used. Addition of excess steam and the required number of reactors to drive the reaction is expensive and it increases the cost of operation. Therefore, it is essential to develop new and novel materials that are robust, active, selective, and tolerant (less susceptible to poisoning and fouling) to contaminants in coal and in biomass.
