Abstract:

The development of mercury-free acetylene hydrochlorination catalysts has great significance to the green development of polyvinyl chloride (PVC) industry in China, among which the gold-based catalysts have attracted broad attention. In view of the problems of high cost and poor stability of gold-based catalysts in industrial applications, their reaction and deactivation mechanism, and the influence of active component and support on their performance are discussed. The research progress of active component improvement and support modification is highlighted. Finally, the development and trends of carbon supported gold catalysts for acetylene hydrochlorination are prospected. We also point out that deeply studying the intrinsic reaction mechanism, simplifying the preparation and regeneration process, and exploring lower cost and high efficiency mercury-free catalysts and their industrialization will be the hotspots in this field.

Key words: acetylene hydrochlorination, gold based mercury-free catalyst, reactivity, catalyst support, catalyst performance

摘要:

乙炔氢氯化无汞催化剂对我国煤基聚氯乙烯(PVC)工业实现绿色可持续发展具有重要意义,金基催化剂因其优良的催化性能而受到广泛的关注。本文从金基催化剂产业化应用存在成本高、稳定性差等问题出发,全面阐述了金基催化剂的反应和失活机理。从活性组分、载体等因素对催化性能的影响出发,概述了多年来金基催化剂的研究进展,重点总结了研究者们从改进活性组分和载体方面入手,使催化剂性能不断提升至工业化应用所做的工作。最后展望了金基催化剂的发展前景,并提出应深入研究内在反应机理,以简化制备及再生过程,探索低成本高效无汞催化剂及其工程化问题是该领域的研究重点。
