METHOD OF COAL HYDROGENISATION Russian patent published in 2008 - IPC C10G1/06 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical technology, namely, to liquefaction of coals and can be used for production of synthetic motor fuels. Method of coal hydrogenisation includes preparing coal-oil paste containing coal, paste-forming agent based on products of thermal modification of high-boiling fraction of coal hydrogenisate in the medium of water vapour on iron oxides at temperature of 450-500°C and iron-containing catalyst subjected to mechano-chemical procession and dispersed by means of ultrasound in fraction of coal hydrogenisation products boiling out at temperature of 180-300°C and taken in amount of 5-20% from the mass of the above paste-forming agent, with its further introduction into paste-forming agent. Then coal-oil paste is heated under excessive pressure in hydrogen medium with further separation of target products.

EFFECT: increased quality of distillate fractions of liquid products of coal hydrogenisation due to reduction of sulfur content without reduction of their yield.
