Abstract

A series of Ni supported on activated carbon are prepared by excessive impregnation and the desulfurization activity is investigated It has been shown that the activated carbonsupported Ni is an efficient solid catalyst for flue gas desulfurization The activated carbon treated by HNO3 exhibits high desulfurization activity and different amounts of loadedNi on activated carbon significantly influence the desulfurization activity The catalysts are studied by Xray diffraction XRD and Xray photoelectron spectroscopy XPS The results of XRD and XPS indicate that the activated carbon treated by HNO3 can increase oxygencontaining functional groups Ni on activated carbon after calcination at 800 °C shows major Ni phase and minor NiO phase and with increasing Ni content on activated carbon Ni phase increases and affects the desulfurization activity of the catalyst which proves that Ni is the main active phase
