A feasibility study is presented for the case where low-sulfur char is produced as a co-product with low-sulfur producer gas in a gasification-desulfurization operation with bituminous coal. Calcium carbonate is used as a sulfur acceptor. Experimental data are also presented to support the design feasibility study. These data show that preoxidized coals are extremely responsive to desulfurization under the conditions used in the feasibility study. It is possible by this method to produce low-sulfur chars containing 0.5% or less sulfur content. The economic evaluation shows that it is possible to produce low-sulfur char at a lower Btu cost than would be the case for complete gasification to low-sulfur producer gas. The value of the char, however, as a boiler fuel is less than that of the producer gas itself. It is, therefore, concluded that there is no clear incentive to produce low-sulfur char as a co-product in a gasification-desulfurization operation. (Author)
