Characterization and performance test of copper oxide supported on activated carbon and attapulgite for flue gas desulfurization

Sorbent of CuO loaded on the support of powder activated carbon and attapulgite for flue gas desulfurization was prepared by impregnation method and characterized by BET, SEM and XRD. The results of BET and SEM showed that the sorbent had a high structural porosity, while sorbent with 20 % CuO loading had the best desulfurization performance although CuO was dispersed at the surface of carrier in a way of multilayer according to XRD patterns.
