Maintenance management is an essential part of effective operation of a coal preparation plant. The key metric is: overall equipment effectiveness can be applied to any coalprocessing facility to measure and sustain performance. The maintenance management system consists of a framework of 3M: man, machine and methods.

HRI is investigating the thermal dissolution of coal and its effects on the mechanism of coal liquefaction in an HCOAL system. The twostage coal liquefaction system consists of a coal slurry preheater which is essentially a short residence time reactor and a liquefaction reactor which can be regarded as a catalytichydrogenationreactor.
