This report describes a single-stage, continuous process for simultaneously removing 90% of the NO/sub x/, 90% of the SO/sub x/, and 99.9% of the particulate material from flue gas from coal-fired combustion sources. The process uses a novel contactor/filter with a moving-bed of copper oxide absorber-catalyst. The contactor/filter was tested at 400/degree/C for NO/sub x//SO/sub x/ removal, and at room temperature for particule removal. The inlet concentration levels were 3000 ppM SO/sub 2/, 500 ppM NO, and 11.5 g/Nm/sup 3/ (5 gr/scf) of fly ash, which correspond to combustion of Illinois No. 6 coal with 20% excess air. The system demonstrated 90% NO/sub x/, 90% SO/sub x/, and 99.9% particulate removal with a Cu/S ratio of 1.02, NH/sub 3//NO ratio of 0.92, gas-solid contact time of 0.52 seconds, catalyst utilization of 88%, and a total pressure drop of less than 1.5 kPa (6 in. of water). These results met the objectives of the program. 18 refs., 34 figs., 5 tabs.
