Effects of preparation methods on sulfidation performance of hot coal gas desulfurizer

With the development of coal gas desulfurization technology at middle or high-temperature,the preparation method of desulfurizers also has many ways.At present there are mainly mechanical mixing method,impregnation method,coprecipitation method,sol-gel method and so on.The preparation method of desulfurizer directly affects its physicochemical properties and then its sulfidation performance.The preparation method of sorbent is reviewed in this paper.The advantages and shortcomings of the various methods are discussed based on the distinction among the sulfide/regeneration performance and the particle sizes,surface characteristics of sorbents.The suitable preparation method of sorbents for different sulfidation condition is sunmmrized up.
