Flue Gas Desulfurization over Copper Oxide Loaded on Complex Carrier of Attapulgite and Activated Carbon

Sorbent of CuO loaded on complex carrier of attapulgite and activated carbon was prepared by incipient impregnation method for flue gas desulfurization. The effects of CuO loading, reaction temperature and components in flue gas on the desulfurization performance were investigated in a fixed-bed quartz reactor. The experimental results indicate that the sorbents of 20 wt% CuO loading has a high desulfurization activity under conditions of reaction temperatures 200-250 oC and 21000 h-1, and O2 is necessary for the high desulfurization activity of the sorbents.
