Summary 　　
In recent years, we made great progresses in desulphurization and updating & generation exchange of desulfurizer when technology was developing in high speed. CoS new-type high-efficiency desulphurization catalyst series,a hi-tech achievement, was developed recently in order to cater present market demand. Whose technical property is up to international leading level. 　　Based on broad survey market of desulphurizer, we analyzed disadvantages and advantages of various desulphurizer home and abroad in details and collected suggestions of users.
In accordance with actual using situation and sulfur content
level in gas, we consummated the formula and using technique to develop CoS new-type high-efficiency desulphurization catalyst series,a hi-tech achievement, was developed recently in order to cater present market demand. Whose technical property is up to international leading level.
