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.

Desulfurization Activity

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.

And Performance

The oily sludge-based adsorbents for flue gas desulfurization were prepared by pyrolysis. Based on benzene adsorptivity, the conditions of pyrolysis process were optimized. The optimum prepared conditions of adsorbent material were in nitrogen atmosphere and 550°C, 4h, 10°C/min for the pyrolysis temperature, pyrolysis time and heating rate, respectively. In this case, the maximum benzene adsorbability was 60.12mg/g. Moreover, the main influencing factor was pyrolysis temperature, secondly was pyrolysis time and finally was heating rate. The sludge-based adsorbents were appropriate for flue gas desulfurization. The sulfur capacity of adsorbents via a flue gas desulfurization test after subsequent processing was about 3% and breakthrough time could keep to 109 min.
