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 xombination of reduction, heat-treatment, or wahing 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 use d as a catalyst.
