Abstract
A method for hydroconversion of coal solids in a solvent by contact with molecular hydrogen and catalyst solids in a reactor. The catalyst solids are catalytically active substances including promoted or unpromoted molybdenum on an alumina support material. The support is characterized by bimodal pore distribution with the average diameter of the smaller pores ranging from about 100-200 angstroms and preferably 120-140 angstroms, and average diameter of the larger pores being in excess of 1,000 angstroms.
