Influence of Non-Pitch Based Activated Carbon on Flue Gas Desulfurization

Abstract

A new type of activated carbon for flue gas desulfurization is obtained by carbonization of non-pitch based formed-coal and characterized by the BET method. The results indicate that the activated carbon with non-pitch binder has higher mechanical strength and sulfur absorptive capacity than the pitch-based activated carbon at adding the same quantity binder. When the addition of non-pitch binder reaches 15.0 wt. %, the activated carbon exhibits the optimum performance. The characterization result shows that the activated carbon with non-pitch binder presents a more developed micro-pore structure, more specific surface area and higher adsorption capacity.
