Abstract
Test results for the production of motor fuel (gasoline, diesel fuel) from coal liquids boiling in the range of 55–425°C are discussed and presented in this article. Test conditions used were: Temperature 400°C; pressure 10 MPa, a liquid hourly space velocity (LHSV) of 0.5 h −1, and a feed rate of 1000 liters of H 2 per liter of feedstock. The product fuels by their physical and chemical properties were similar to petroleum-derived products. Industrially used alumo-nickel-molybdenum catalyst (Russia) did not lose its activity in hydrotreatment of coal liquids during runs lasting 2000 hours and the coke deposition on the catalyst amounted to 16–18% (by weight). Motor fuels production from brown coal hydrogenation liquids at low hydrogen pressure (to 10 MPa) is being developed in Russia at the ST-5 experimental plant, which has a daily capacity of 5 to 7 tonnes.
