According to this search of effective technologies ofchemical processing heavy and hard hydrocarbon raw-material is actual. The aim of thenesearch was studying processes of the catalytic hydrogenation of coal with catalytic additives.As a hydrogen processes don a wide fraction of coal pitch from Shubarkol coalfield’s(Kazakhstan) coals was used in half-cocking process. Before carrying out the catalytichydrogenation the coal pitch was mechanochemically processed in cavitation-wave field.By the obtained data we can talk about high conversion degree of organic mass of coal andoutput of liquid products of coal: yield of fraction until 300°C is 60,4%, hydrogenate – 40,5%.Pyrite is an active catalyst, stechiometric pyrrotine is a working state of iron-sulfidecatalyst in the process of hydrogenation and as a result of reaction with molecular hydrogenatomic hydrogen is generated. However in /1-2/ works it is shown that iron sulfate is moreactive and surface sulfateFe O [ SO2−4] that is formed by oxidation of sulfide is active site ofcatalyst on the base of iron in coal hydrogenation processes. Thus, high activity of catalysts isalso explained by formation of iron complex23Fe O [ SO] . Formation of given complexacting as an active catalyst it is determined that with the help of electronic microscopy.Thus, comparative analysis of data on process of coal hydrogenation shows that chosenfraction of coal pitch by donor ability can be compared with traditional donor of hydrogen –tetraline. Also, it is determined that possibility of using new bifunctional catalysts for coalhydrogenation and wide fraction of coal pitch which have high selectivity to output of lightand middle fraction (300°C) with low amount of polycyclic hydrocarbons.References1.
