Abstract

Analysis of the state of Ukrainian Coal Industry and modern tendencies compiling coal blends for coke plants clearly highlights the need to solve the problem of rational use of domestic coal. This work has shown an opportunity to expand the resource base of coking due to an increase in the blends the share of cheap low-quality domestic coal.

Еxperimental-industrial coking of unconventional coal blends containing a maximum of weakly coking components and caking Donetsk coal of reduced type have been carried out. It has been obtained the desulfurization effect (45–50 %) for cokes derived from proposed coke mixtures Jrc+Glrc=50:50 and=70:30 in industrial environments. It is shown that the use of these mixtures as blends allows to obtain  cokes suitable on the sulfur content – 0,95–1,14 wt %  with high mechanical strength (P25=90,2–91,7 %). This coke can be used as a special kind of coke in many industries and as a coke for the domestic market. The addition of coal tar pitch in the proposed coal mixture can improve the strength properties of coke.

The use of low-quality domestic coal will, saving quality coal, significantly reduce the cost of coke.
