Abstract

The results of studies on the determination of the effect of ozonization on the hydrofining of coal tar from the coal of the Shubarkol deposit are reported. It was established that preliminary ozonization for 60 min makes it possible to increase the total yield of liquid products by 44.8% in the subsequent catalytic hydrogenation conversion of tar (5 MPa, 450°C, and a pseudo-homogeneous Mo-containing catalyst) and to increase the yield of a fraction with boiling points to 180°C by 17.7%, as compared with their concentrations in the parent tar.
