In Two Stage Liquefaction, coal is dissolved and partially hydrogenated in the short contact time first stage using process derived solvent as vehicle oil. The unreacted coal and ash are removed by antisolvent deashing and the product oil is upgraded in a separate catalytic reactor. This scheme is proposed as a means of converting coal to distillate with higher yield, reduction in hydrogen consumption, and minimal catalyst poisoning since no catalyst is used in the first stage. A number of papers have been published discussing various aspects of this technique. In this investigation a disposable ore catalyst consisting of a mixture of bauxite, limonite, and molybdenum ore concentrate is added to the first stage and its effect on the yield and quality of the product oil from the second stage is studied.
