Abstract
Twenty-four kinds of coking coals which have different ranks are selected to investigate the sulfur transformation during coking process. The form sulfur in coals and cokes are determined by wet chemical method. The results show that the conversion of total sulfur during coal coking process is influenced by volatile content of coal and the content of the inertinite. The conversion of total sulfur is high for the large volatile content in coal. There is some linear correlation between the average conversion of total sulfur and the average inertinite content, this paper presents that the average conversion of total sulfur is high for the low average inertinite content. We also foud that coke sulfur depends primarily on the amount of coal sulfur, and the transformed capability of sulfide sulfur is stronger than that of the organic sulfur conversion for coal during coking process.
