With the development of domestic coal gasification technology,the volume frac-tion of CO in coal to synthesis gas is increasing,which puts forth higher requirements for the sulfur-tolerant shift technologies and reactors.Taking the application of Shell gasification shift technology under high content CO condition as an example,advantages and disadvantages of several typical sulfur-tolerant shift technologies and the sulfur-tolerant shift reactors are com-pared.The requirements for sulfur-tolerant shift catalysts and many problems that need to be solved in the current application process are analyzed in depth.Based on this,this article pro-poses that the isothermal sulfur-tolerant shift technology and its reactor are more suitable for sul-fur-tolerant shift catalysts,which can effectively solve the current problems.The future develop-ment of the sulfur-tolerant shift technologies under high CO content condition is prospected.
