Innovative Catalyst Design Overcomes High Dust SCR Challenges


Ash accumulation during coal power generation, especially in “high dust” environments in the flue gas, can lead to erosion and plugging of the SCR catalyst with subsequent ash build-up atop the catalyst layers. Coal-fired power plants globally utilize a range of opportunity fuels to produce the lowest cost power. These coals have varying levels of ash, which can be a detriment to a power plant’s downstream air pollution control equipment, specifically SCR catalysts used to reduce NOx emissions.

CORMETECH, Inc., the world’s leading SCR catalyst manufacturer, has brought its years of experience in SCR catalyst development to offer an innovative solution that surpasses currently available catalyst technologies. The unique CORMETECH DUSTBUSTER® SCR catalyst consists of optimized channel geometries that facilitate the flow of ash-laden flue gas through catalytic surfaces without compromising on the DeNOx and SO2 performance, product reliability, and catalyst life cycle benefits of Honeycomb platforms. Furthermore, the uniform, large hydraulic diameter rectangular openings deliver optimized aspect ratios to prevent dust build up and catalyst pluggage inside the SCR reactor.
