Catalytic fabric filtration for simultaneous NO{sub x} and particulate control. Quarterly technical progress report, October 1--December 31, 1992
The EERC approach to meeting the program objective involves the development of a catalytic fabric filter for simultaneous NO{sub x} and particulate control. The idea of applying either permanent or throwaway catalysts to a high-temperature fabric filter for NO{sub x} control is not new. However, advances at OCF have shown that a high-activity catalyst can be applied to a high-temperature woven glass cloth resulting in a fabric filter material that can operate at temperatures higher than the maximum operating temperatures of commercially available, coated glass fabric. The NO{sub x} is removed by catalytic reduction with ammonia to form nitrogen and water. The catalyst employed at this time is vanadium/titanium, but the exact catalyst composition and the unique method of applying the catalyst to high-temperature glass fabric are the property of OCF. Other catalyst options are being evaluated by OCF in order to improve catalyst performance and minimize catalyst cost. Bench-scale experimental results to date have shown that over 90% NO{sub x} removal can be achieved, the catalyst/fabric has promising self-abrasion characteristics, and the potential exists for substantially reduced cost when compared with conventional SCR/fabric filtration technology. However, development of the technology requires further evaluation of air-to-cloth ratio, ammonia slip, SO{sub 2} oxidation to SO{sub 3}, temperature cycling, catalyst-coated fabric preparation, fuel impacts, fabric cleaning (reverse-gas versus pulse-jet), catalyst life (poisoning and resistance to erosion), and filter performance/life (particulate control, differential pressure, and durability).
