| Abstract: | The effects of preparation technique and reaction conditions of Ag-SAPO-34 catalyst on the catalyst activity are studied.The Ag-SAPO-34 catalyst which is active at low temperature has been prepared, on which the highest conversion of NO reduction to N2 is 74.1% at the oxygen concentration of 3.6Vol.% and the temperature of 340℃. The most suitable pH value of the ion exchanged AgNO3 solution and ion exchanged temperature are 7.0 and 40℃ respectively, and the calcined temperature is 600℃. The catalytic activity rises with the concentration of C3H6 and decreases with GHSV. |
