The Influence of Organic and Inorganic Additives on the Specific Electrical Resistance of Coke

This study aimed to evaluate the effect of both inorganic (boron carbide nanopowders and silicon carbide (carborundum) and organic lean (petroleum coke) additives on the quality of coke produced in a laboratory furnace, as well as on its electrical properties. Analyzing the results of the quality assessment of the obtained coke, it can be argued that the addition of a fixed amount $(0.25-0.5 \ wt.\%)$ of non-caking nanoadditives allows to regulate the process in the plastic state in order to increase the coke strength.

Production and quality of blast furnace coke in Ukraine

This research displays the state of metallurgical coke production in Ukrainew with special attention to the raw material base for production of coke and its quality. Besides the following essay deals with the detailed analysis of preparation methods of coal charge for coking, including thermal treatment and stamp charging and formulates the main ways of upgrading coke quality considering the rational technology of coking.
