DESULFURIZATION OF COKE OVEN GAS BY MIXING ZnO POWDER INTO COAL

TANG Hui qing, GUO Zhan cheng, YAO Yu, LIU Yu xing (Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100080, China)  
On the basis of thermodynamic simulation, behavior of H 2S removal from coke oven gas by mixing znic oxide into the coal and the effect of the additive on the coke quality have been investigated The experimental results show that in the stage when coal converts into semicoke, hydrogen sulfide concentration in COG decreases with the increase of zinc additive in coal And an optimum amount is about 40% excess of the stoichiometric amount of zinc additive needed in coal In the stage when semicoke converts into coke, hydrogen sulfide concentration in COG decreases with the increase of zinc additive in coal, the reason of which is the zinc oxide retented in the semicoke is more easier to decompose under the same condition than zinc sulfide The addtive of zinc oxide in coal has little deleterious effect on coke quality
