The present status of coal liquefaction technology (ST-5 and ST-75 projects) in Russia was investigated. The ST-5 project (7-10t-coal/d process development unit) was promoted by Fossil Fuel Institute and its opearation study at Tula was begun in 1986. The coal sample used was mainly Borodinsky brown coal from Kansk -Achinsk basin, which is abundantly reserved in the province of Krasnoyarsk.
The process is characterized by the low hydrogen pressure of less than 10MPa, the use and recovery of higher active and dispersion molybdenum catalyst, the addition of organic compounds for the suppression of retrogressive reaction, and the use of hydrotreated recycle solvent. The conversion of coal into gas, water and liquid fractions was more than 70 wt% daf under standard reaction conditions.
The ST-75 project (100t-coal/d pilot plant) was started near Beryozovo deposit in Kansk-Achinsk basin in 1986 to produce gasolin, diesel and jet fuels. However, the project was quited in 1992 for financial reason and a part of the equipments purchased was transfered to the ST-5 plant.
