Аннотация: It is suggested that the pitch, obtained in the course of coal thermal processing, should be used as binder for manufacturing calcined anodes in aluminum industry. The investigations were carried out to determine the effect of brown and black coal mechanical processing on the degree of its organic matter conversion under thermal autoclave curing in solvent medium. It was established that under temperature of 380°C and pressure of less than 2.0 MPathe yield of the quinoline-soluble fraction of pitch amounts to 80 % for brown coal and up to 92 % for black coal of gas fat rank. It was found that the hydropercussion/cavitation processing of the water-coal suspension within a period of 15 minutes at a frequency of 55Hz increases the degree of conversion of the coal organic matter by 4-6% on average. The index of the coke residue in the pitch obtained from mechanically activated coal also increased by 3-4 %.
