Abstract
The mechanical strength and pore structure of special-purpose coke are determined in classical and thermooxidative coking (heating rate 2.3 and >30°C/min, respectively). The relationship between the coke’s strength and porosity is established. By mercury porosimetry, the volume of the pores and their distribution within the coke are determined. In the thermooxidative coking of long-flame Shubarkol coal, the pore size of the special-purpose coke obtained (800–1200 nm) is an order of magnitude greater than that of regular coke (100 nm).
期刊介绍：
The journal publishes scientific developments and applications in the field of coal beneficiation and preparation for coking, coking processes, design of coking ovens and equipment, by-product recovery, automation of technological processes, ecology and economics. It also presents indispensable information on the scientific events devoted to thermal rectification, use of smokeless coal as an energy source, and manufacture of different liquid and solid chemical products.
