Flue Gas Desulfurization with CuO/AC Desulphurizer Using Cocoanut Shell Activated Carbon as the Support

CuO/AC desulphurizers were prepared using cocoanut shell activated carbon as the support and a fixed-bed flue gas desulfurization(FGD) reactor was set up,so as to study the influence of following factors on FGD performance of the desulphurizer,such as the calcination temperature,Cu loading capacity,desulphurizing temperature and gas component,etc.Results show that for higher FGD performance of CuO/AC desulphurizer,the calcination temperature would better be kept at about 250 ℃,Cu loading capacity in 5%-7.5%,desulphurizing temperature in 200-250 ℃ and O2 concentration in flue gas at a moderate degree.Regenerated desulphurizer would have better performance if the regeneration temperature is kept at 300 ℃,however,its desulphurization reactivity is worse than the original CuO/AC desulphurizer.
