ABSTRACT:
When low-quality iron ore is used as a coal liquefaction catalyst, in order to improve its catalytic activity it is subjected to one or a combination of reduction, heat-treatment, or washing with or immersion in water for a long period of time so as to remove catalyst poisons before it is used as a catalyst. When high-quality iron ore is used, it is first reduced with carbon monoxide and then used as a catalyst.
