摘　　要：羰基硫广泛存在于高炉煤气、焦炉煤气、黄磷尾气和各种工业废气中,对人体健康、工业生产和生态环境都会造成巨大的危害。催化水解法由于效率高、能耗低等特点受到了研究人员的广泛关注,开发催化活性好、稳定性高的水解催化剂成为研究的重点。铝基催化剂是目前工业上应用最多的水解催化剂,其中氧化铝不仅具有表面积大、活性高等特点,而且具有催化活性,而铝基类水滑石由于其独特的结构和优良的性能,同样受到了广泛的研究。但在实际应用中,中毒、失活过快仍是困扰水解催化剂的一大问题。本文介绍了近些年来铝基水解催化剂的相关研究成果,包括目前较为成熟的工业催化剂及含铝类水滑石催化剂,同时介绍了不同金属改性对水解催化剂的影响,解释了羰基硫水解的气氛效应,最后综述水解反应的动力学和机理,旨在为后续高活性、高稳定性水解催化剂的设计与研究提供参考。Carbonyl sulfide is widely found in blast furnace gas,coke oven gas,yellow phosphorus tail gas and various industrial waste gases,which will cause huge harm to human health,industrial production and ecological environment.Catalytic hydrolysis had received wide attention due to its good efficiency and low energy consumption.The development of hydrolysis catalysts with good catalytic activity and high stability has become the focus of research.Aluminum-based catalysts are the most widely used hydrolysis catalysts in industry at present.Among them,alumina not only has large surface area and high activity,but also has catalytic activity.Aluminum-based hydrotalcite has also been widely studied because of its unique structure and excellent performance.However,poisoning and too rapid deactivation are still a major problem that plagues hydrolysis catalysts in practical applications.This paper introduces the relevant research results of aluminum-based hydrolysis catalysts in recent years,including the more mature industrial catalysts and aluminum-containing hydrotalcite catalysts,as well as the effects of different metal modifications on hydrolysis catalysts and explains the atmospheric effects of carbonyl sulfur hydrolysis.Finally,the kinetics and mechanism of the hydrolysis reaction are reviewed,which can provide a reference for the design and research of subsequent hydrolysis catalysts with high activity and high stability.
