Abstract

Based on the data of the elemental constituents of the coal distillates and reaction products of the hydrotreating pre-defenolized feedstock in the presence of 5% Mo/Ni-Re catalyst, as well as the material balance of the production of diesel fuel components from fractions with a boiling point of 180-360 ° C the thermal effects were calculated. It was demonstrated that in the process of hydrotreating of coal distillates with boiling point at the range of 180-360 °С the values of thermal effects are 200-220 kJ/kg depending on the composition of the feedstock. The observed values of thermal effects of reactions of the hydrotreating of coal distillates with different fractional composition can be used for the designing of the appropriate processing units and for the construction of reactors. It also can be used for the evaluation of the chemistry reactions occurring during the hydrotreating of coal fractions depending on the nature of the catalytic reactivity of catalysts, as well as for the development of recommendations for using an effective catalyst.
