ZHU Yin-hui1, ZHANG Xian-lin1, LI Wen-hong1, BIAN Xi-mian2(1.Hebei College Of Industry And Technology,Shijiazhuang 050091,China; 2.HeBei Province Institution of Supervision And Inspection Product Quality,Shijiazhuang 050051,China)By simulating industrial coking process,in view of a high-sulfur coal inspected the different types of gas flow and heating rate,coke oven gas to return to the process of coking coke in the sulfur content of change. The results showed that all-coking process of H2,CH4 and N2 gas can inhibit thermal gasification of solid sulfur return coke,the coke H2 achieve desulfurization of the largest,followed by CH4 and N2; increased gas flow,reducing the heating rate is Sulfur helps make the shift to gas,solid coke so that the distribution of sulfur in lower sulfur content in the solid coke changes also show that better results H2,3.0,1.5℃/min heating rate will enable the two of sulfur content of coke decreased 0.36 percent and 0.39 percent to 0.46 percent to 0.56 percent.
