Abstract

In the course of study the optimal conditions of conduction of the process hydrogenization are found. Optimal temperature for preparation of motor oils from chark chemical tar is 4000С. On the increase of temperature from 3500С to 4000С the yield of liquid products on Mo-containing catalyst increases from 47.1 mass. % to 65.2 mass. % compared to the yield of liquid products obtained without the catalyst. The yield of gasoil fraction constitutes 15 mass. %. Optimal quantity of catalyst for preparation of liquid products from the tar is 0.05 mass. %. According to the results of study the catalytic effect of synthesized from emulsion catalyst appears at low concentration of molybdenum (0.05 mass.%). But the double increase of concentration of molybdenum weakly effects the improvement of indicators of the process.
