摘要：
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. © 2022 Chemical Industry Press.
