Removal of NOx and SO2 by CuO/gamma-Al2O3 sorbent/catalyst in a fluidized-bed reactor
Selective reduction of NO and the simultaneous removal SO2/NO by CuO/gamma-Al2O3\ sorbent/catalyst were carried out in a fluidized-bed reactor. The optimum temperature ranges for NO reduction over the fresh and sulfated CuO/gamma-Al2O3 catalyst are found to be 250-300 and 300-450 degrees C, respectively. The NO removal efficiency with the sulfated catalyst is somewhat higher than that with the fresh catalyst. The amount of optimum Cu/S is found to be 1.5 in the simultaneous removal of SO2/NO. The optimum temperature range for the simultaneous removal of SO2/NO by CuO/gamma-Al2O3 sorbent/catalyst in the reactor is 350-400 degrees C based on the SO2 and NO removal efficiencies (> 90%) and N2O formation (< 10% of NO in feed).
