Show 6. Conclusion New desulfurizing agents were developed for the removal of CS2 and COS from coke oven gas in a room temperature, normal pressure dry bed process. The results were summarized as follows: (1) CS2 component is effectively removed by an absorbent comprised of a amine and a calcium silicate carrier. (2) The elimination of COS is achieved by the use of an alumina catalyst which causes the conversion of COS into H2S by hydrolysis. The absorbent for CS2 removal has been applied to the commercial refining equipment for city gas with satisfactory results. References 1) J.I.Ch.E: Kagaku Kogaku Binran, Maruzen, (1988), p.532.
