ABSTRACT:
A new catalyst, which is Ni-Mo metal loaded on zeolite-alumina carrier, provides efficient hydrotreatment of solvent for coal liquefaction and cracking of high boiling fractions, especially high boiling n-paraffins, whereby undesired accumulation of n-paraffins can be prevented and liquefaction operations can be stably performed over long periods of time.
