VANADIA-BASED DENOX CATALYSTS AND CATALYST SUPPORTS |
摘要 |
A vanadia-based catalytic composition for reduction of nitrogen oxides includes a titania-based support material; vanadia deposited on the titania-based support material; a primary promoter comprising tungsten oxide, molybdenum oxide or combinations thereof; and an amount of phosphate to achieve a mole ratio of phosphorus to vanadium plus molybdenum of about 0.2:1 or greater. A zirconia, tin or manganese oxide can be added to further inhibit the volatility of molybdenum. Results show low SO2 oxidation rates and excellent NOx conversion and/or molybdenum stability. |
