The selective catalytic reduction (SCR) reaction belongs to the gas-solid multiphase reaction, and the adsorption of NH3 and NO play an important role in the reaction. The adsorption behaviors of NH3 and NO were studied with the diffuse reflectance infrared transform spectroscopy (DRIFTS) methods; these results showed that there were obvious adsorption phenomena of NH3 and NO on the catalysts. NH3...
CuO/gamma-Al2O3 granular catalysts were synthesized by the sol-gel method. Performance of the CuO/gamma-Al2O3 catalysts for the selective catalytic reduction (SCR) was explored in a fixed bed adsorption system. The optimum temperature ranges for SCR of NO over the fresh CuO/gamma-Al2O3 catalyst are 250~450degC. The maximum activity maintains near to 99% at 350degC. The operating temperature range...
Adsorption experiments of vapor-phase elemental mercury were carried out using bromine and iodine modified Kaolin, Zeolite, Bentonite and Chitosan in a laboratory-scale fixed-bed reactor. VM3000 online mercury analyzer was applied to detect the inlet and outlet Hg0 concentrations. The characterizations of the sorbents were analyzed using Fourier transform infra-red spectroscopy. The results indicated...
