HIGHLY ACTIVATED COKE POWDER AND PROCESS FOR PRODUCING THE SAME

摘要

A highly activated coke powder comprising abraded particles separated from regenerated activated coke particles having heightened activity imparted by adsorption and thermal desorption of sulfur oxides in a dry flue-gas desulfurization process, characterized by having been regulated in particle size so that the average particle diameter is 10 to 15 µm and the content of particles having a particle diameter of 0.3 to 4 µm is 10 to 25 wt.% based on the whole particles. The coke powder can efficiently adsorb the dioxins, mercury, and other heavy metals contained in discharge gases to make the gases harmless. The powder can be provided at low cost because it comprises regenerated activated coke particles.
