A coal liquefaction process employing a first stage liquefaction step catalyzed by a soluble molybdenum-containing organophosphorodithioate catalyst is disclosed. In some embodiments, two consecutive liquefaction steps employ a molybdenum-containing organophosphorodithioate catalyst operating at a relatively high liquefaction temperature. In other embodiments, a second liquefaction process step operating at a relatively low temperature employs a hydrocracking catalyst to upgrade materials obtained from the first soluble catalyst liquefaction step. In some embodiments, an interstage gas separator removes gases such as carbon dioxide produced in the first liquefaction step from a partially liquefied mixture prior to further liquefying the mixture in the second liquefaction step.
