Abstract
The porous structure of high-temperature coke obtained on the basis of coal of different grade composition from the Kuznetsk Basin was studied. It was established experimentally that the specific surface of high-temperature coke decreases with an increase in the stage of coal metamorphism. It was determined that coke with the maximal relative volume of micropores is formed from low-metamorphosed and weakly caking coal. During the carbonization of coal at the medium stages of metamorphism, dominant development is exhibited by transport pores.
