摘　　要：论述了脱除羰基硫的各种方法,包括还原法、水解法、吸收法、吸附法、光解法及氧化法等,展望了COS脱除技术的研究趋势。指出ZrO2与TiO2、Al2O3混合制备新的多组分催化剂,以及引入铁一类助剂来降低催化剂表面的亲水性进而降低催化剂的失活程度是COS脱除技术研究可能的新方向。Methods of removing carbonyl sulfide,including reduction, hydrolysis, absorption, adsorption, photolysis, oxidation, etc, were reviewed and the research trends were prospected in this paper. It was indicated that development of multi-element catalysts via mixing ZrO2, TiO2, Al2O3 and introducing assistants such as iron to reduce the catalyst surface hydrophilic of catalysts and thus reduce the extents of deactivation maybe the new aspect in COS removal.

关 键 词：羰基硫 脱除技术 催化剂
