Abstract:

The laboratory crucible cokemaking test was made with 56 kinds of coals for cokemaking in WISCO, the sulfur conversion relationship between coal and coke was studied so as to lower sulfur content in coke and to rationally use coal. The results from study showed that as for single kind of coal for cokemak?鄄ing, the sulfur conversion rate (ΔS ) between coal and coke was lowered with the increase of volatile matter （Vd）, it had better correlation; the proportional factor (ΔS/K ) between sulfur in coke and sulfur in coal for coking was increased with the volatile matter （Vd）. Whether it was the single kind of coal for coke making or coal blend, their sulfur in coke was increased with the increase of sulfur in coal for cokemaking, and it had good correlation.
