Abstract
Optical microscope and X-ray diffraction study were conducted to investigate the microscopic mechanism of coke size distribution. The results show that an increase in coke size resulted in a slight decrease in moisture and an increase in the volatile matter content. However, the mineral catalysis index (MCI) varied slightly with the change in coke size. Besides, the cell dimension did not change much with the coke size variation. Furthermore, cell spacing and graphitization degree increased when the coke size decreased. Therefore, it is possible to improve the coke size distribution and control the coke graphitization degree in the coking process.
