03 Gaseous fuels (derived gaseous fuels) undesirable atmospheric pollutants.
In the same way, the efficiency of integrated gasification molten carbonate fuel cell (IGFC) power plants remains unaffected by ammonia, but nitrogen oxide is generated during 99iQ2502 combustion of the anode exhaust gas. It is therefore important to remove CHEMRECTM black iiauor aasification ammonia from hot coal gas before it is burned in a turbine or fuel cell. Zinc-based hydrogen sulfide (HzS) sorbents could be combined with NH3 decomposition catalysts, reducing the process steps in a hot-gas cleanup subsystem. The study aims to develop sorbent-catalysts that remain stable for NH3 decomposition in addition to H2S removal under cyclic sulfidationregeneration conditions at temperature of SOO-750ยฐC. After preparing and testing a number of sorbent-catalysts, the most obvious choice are zinc oxide-based sorbent-catalysts containing nickel. The best candidates to date consistently removed 99% or more of the HIS from a simulated coal gas containing 1 ~01% H2S and were regenerable for multi-cycle operation at 650-750ยฐC. The tested sorbent-catalysts also exhibited moderate catalytic activity for NH2 decomposition at 700ยฐC. even in the presence of 1% HIS.
