Study of sulfur dimensional distribution in coke
焦炭中硫的空间分布规律研究

The rule of sulfur dimensional distribution in coke was studied by simulating the industrial coking process using coking coal. The result show that the content of organic sulfur and inorganic sulfur increases gradually from the center to the brim at the same height of the coke column. The content of organic sulfur and inorganic sulfur in the crack section is higher than that in the interior section at the same position. The increased quantity of organic sulfur and inorganic sulfur is about 0. 035% and 0.08% in the test with a diameter 230 mm coking reactor. XPS analysis shows that the different content of organic sulfur and inorganic sulfur is resulted from the different content of sulfide sulfur and thiophenic sulfur. The rule is approved further by the two-dimensional simulation experiment.
