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