煤的清洁转化利用符合中国的能源结构，高温煤气脱硫是提高能源利用率的关键技术。本文综述了单一金属氧化物和复合金属氧化物干法脱除 H2S 的研究进展，对比分析了单一金属氧化物在脱硫效率、使用温度和再生方面的优缺点，指出由于单一金属氧化物脱硫剂不能满足实际生产需要，因此兼有单一金属氧化物优点的复合金属脱硫剂成为未来研究方向。同时，论述了复合金属脱硫剂的制备原则、脱硫效率及再生等方面的研究状况。在此基础上，重点对铁酸锌和钛酸锌两种具有代表性的复合脱硫剂及其他复合金属脱硫剂进行了介绍。

Clean utilization of coal is an important component of China’s energy structure,and desulfurization of hot coal gas at a high temperature is the key technology to improve its utilization efficiency. This paper summarizes the research progress of removal of hydrogen sulfide from coal gas by the dry method with metal sorbents and complex metal sorbents. The characteristics of metal sorbents are analyzed,including desulfurization efficiency,test temperature and regeneration properties. The metal sorbents cannot meet the practical needs,so latest researches on the complex metal sorbents with the advantages of metal sorbents have become a significant field in recent years. Then,the research status of complex metal sorbents are illustrated , including principles of preparation , desulfurization efficiency and regeneration properties. The study on zinc ferrite sorbent,zinc titanate sorbent and other complex metal sorbents are introduced.
