Zinc titanate sorbents to remove H₂S in the coal gasifier gas were formulated and their attrition resistances and reactivities were studied through the multicycle operation in a laboratory scale. In the preparation of sorbents Co₃O₄ and NiO were added to the formulation for the development of the more efficient sorbents at the mid-temperature operations as well as MoO₃ was added for the improvements in the sorbent attrition resistance. Attrition test for prepared sorbents were performed by utilizing the ASTM air jet sttrition method. The desulfurization tests for the new formulation were also carried out at 480℃ to make a comparison between the sulfur capacities of the new sorbents and those of the first generation of sorbents developed for high temperature operating condition. The 50-cycles of the sulfidation and regeneration for a superior formulation, which is selected based on the attrition tests, were performed at 480℃ to investigate its chemical and physical properties. The result showed that the desulfurization efficiency of the selected sorbents were regenerated at 580℃ and investigated the changes of the physical properties of the sorbents after the multiple cycle.
