Abstract: The catalytic oxidation of HCl is gaining increasing application and industrial prospects in the chlorine-related industry. CeO2-based materials have been regarded as the most promising catalysts for HCl oxidation due to their excellent characteristics such as low-cost,sintering-resistant and anti-chlorination. After a brief introduction of the chlorine circulation process,this manuscript discusses different ceria-based catalytic materials for HCl catalyzed oxidation,including CeO2 catalyst,modified CeO2 catalyst and CeO2 as catalyst promoter. Special focus has been put on the surface reaction mechanism of HCl oxidation on CeO2. Considering the current research condition,this review also provides some future prospects for promoting the activity of CeO2-based catalysts in HCl oxidation.

Key words: catalysis, oxidation, chlorine circulation, cerium oxide(CeO2), chlorine

摘要: 氯化氢催化氧化技术在副产氯化氢的处理和利用方面有着巨大的应用价值和良好的工业前景。CeO2基催化剂因其廉价、不易烧结及抗氯化性能优良等诸多优点,被认为是目前最具有应用前景的氯化氢氧化催化剂之一。本文简要地介绍了氯化氢氧化制氯循环工艺,评述了近年来用于氯化氢氧化反应的CeO2基催化材料,包括CeO2催化剂、掺杂改性CeO2催化剂以及CeO2作助催化剂等。同时在文中还对CeO2基材料催化HCl氧化的表面反应机理进行阐述。最后结合目前的研究现状,对如何进一步提升CeO2基催化HCl氧化的反应活性进行了展望。
