Catalytic coal gasification (ccg), one of the most promising third generation coal conversion processes, is based on reaction of coal and steam in the presence of an alkali metal catalyst to achieve high production of methane at a rate equivalent to second generation high British thermal unit process, but at lower temperatures and pressure. Additional advantages include reduced energy requirements, the elimination of a separate methanation reactor, and the ability to process caking coals. At present, few data are available to aid in selecting metal and refractory materials for reliable, low-cost services under the conditions prevailing in the ccg reactor itself. The objectives of this research are to determine the effect of ccg environments on metal and refractory materials of construction by exposure to ccg reactor conditions in a laboratory simulator and to identify the attack mechanisms of ccg environments on metals and refractories so that materials offering improved performance at lower cost can be identified.
