Abstract:

Studies show that during coking,for coking coal with different metamorphic degree,the initial separating out temperatures of sulfur are different,the variation rules of total sulfur and organic sulfur are the same as the temperature changes,and the desulfurization rates from iron sulphide are the same as the temperature increases.To control the sulfur content in coke,coal with high sulfur content shall be properly used for coking based on sulfur content of various form and the desulfurization rule of organic sulfur during coking.
