Abstract
Special CoMo/Al2O3 catalysts were prepared for testing in coal liquefaction: a conventional CoMo/Al2O3 catalyst, one containing Zn as a second promoter and one having the alumina acidified with fluorine. Their activities were compared with that of red mud. The experiments were conducted in a stirred autoclave with a subbituminous coal and solvent (tetralin, anthracene oil or creosote oil) at 425 degrees C and 17 MPa. The liquefaction products were fractioned into oils, asphaltenes and preasphaltenes with pentane, toluene and THF. The Co(Zn)Mo/Al2O3 catalysts have far higher activities than red mud. Zn and fluorine have beneficial effects on the catalyst activity. Coal tar distillates give higher conversions and oil + gas yields than tetralin when the prepared catalysts are used.
