Catalytic fabric filtration for simultaneous NO{sub x} and particulate control. Quarterly technical progress report, April 1--June 30, 1992
The objective of this program is to develop advanced concepts for the removal of NO{sub x} from flue gas emitted by coal-fired utility boilers, or for the control of NO{sub x} formation by advanced combustion modification techniques. Funded projects are required to focus on the development of technology that significantly advances the state of the art using a process or a combination of processes capable of reducing NO{sub x} emissions to 60 ppm or less. The concept must have successfully undergone sufficient laboratory-scale development to justify scaleup for further evaluation at the pilot scale (not to exceed 5 MWe in size). 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.
