The object of this program is to investigate the desulfurization of mild gasification char using H{sub 2}CH{sub 4} mixtures in a laboratory-scale experimental study. Mild gasification is a coal conversion technique which produces solid, liquid, and gaseous co-products. Char is the major co-product, about 60% of the dry coal yield. Form coke for steelmaking and foundries presents the best potential high-value markets for chars from eastern bituminous coals. Conventional metallurgical cokes generally contain about 1 wt% or less sulfur. Mild gasification char from high-sulfur Illinois coals must be upgraded to meet these criteria. One method to accomplish this is desulfurization with reducing gases derived from the mild gasification co-product gases. Because form coke has a market value up to $200/ton, it can accommodate desulfurization costs and still be economically attractive. The desulfurization can be performed either on the granular char or on formed-briquettes.
