Abstract |
The report gives results of a study of vanadia-alumina and iron oxide-chromium oxide-alumina catalysts for the reduction of NO with NH3 in simulated flue gas. Optimum catalyst compositions were 15% V2O5 on Al2O3 and 10% Fe-Cr oxides on Al2O3 with an Fe/Cr ratio of 1/9, respectively. Both catalysts were selective for the reduction of NO to N2 in the presence of O2. Both were shown to be sulfur-resistant during total periods of operation of 648 hours for V2O5 and 1052 hours for Fe-Cr in the presence of SOx. Typical conversion levels for V2O5 and Fe-Cr catalysts operating at 400 C in simulated flue gas containing 1000 ppm NO, 1000 ppm NH3, in the presence of SOx, were about 90 and 80%, respectively, at 20,000 per hour space velocity. Rate expressions for both catalysts have been developed for design use. A tabulation of recent publications in the field of NOx catalysis (particularly selective reduction with NH3) is presented. |
