Abstract. In this work the results of research are presented of humic preparations used as natural polymer modifiers for the palladium catalysts. New nanosized catalysts on the basis of palladium - potassium humate are synthesized, extracted from coals of Oy-Karagay and Kunming fields (People's Republic of China). The highest activity is shown on the catalysts of 0,8 % of the Pd- Humic acids (Oy-Karagay) of 1 % / bauxite-094.

In the course of study the optimal conditions of conduction of the process are found. Optimal temperature for preparation of motor oils from chark chemical tar is 400 °С. On the increase of temperature from 350 °С to 400 °С 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 affects the improvement of indicators of the process.
