In-service insights into flue gas oxidation catalyst for natural gas-fueled power generation applications
Abstract
A natural gas-fueled power generation application is sustainable to the degree that its flue gas oxidation catalyst operates with robust high performance. This study of an industrial catalyst revealed distinct application features, namely: (i) combined cycle operation generated a low contaminant accumulation that strongly correlated with performance reliability, and (ii) simple cycle operation generated a high contaminant accumulation that weakly correlated with performance reliability. Operation type also determined the influences of catalyst design on performance reliability. Combined cycle operation favored catalysts with sufficient PGM loading and high cell density substrate, while simple cycle operation favored catalysts with higher PGM loading and low cell density substrate.
