摘　　要：1-氯-1,1-二氟乙烷(HCFC-142b)催化裂解制备1,1-二氟乙烯(偏二氟乙烯,VDF)的方法虽已实现工业化,但因所用催化剂在高温下易积碳,导致催化剂失活,或因添加促进剂导致裂解时造成环境污染等问题而存在应用缺陷。本文通过对比研究金属及其盐类催化剂和非金属类催化剂应用于HCFC-142b催化裂解及抗结焦性能,为HCFC-142b裂解催化剂的选择及未来的研究方向提供参考。Although the method of catalytic cracking of 1-chloro-1,1-difluoroethane(HCFC-142b)to prepare 1,1-difluoroethylene(vinylidene fluoride,VDF)has been industrialized,it has application defects due to the easy carbon deposition of the catalyst at high temperature,which leads to the inactivation of the catalyst,or the environmental pollution caused by the addition of accelerator during cracking.In this paper,the application of metal and salt catalysts and non-metal catalysts to HCFC-142b catalytic cracking and anti-coking performance is compared and studied,which provides a reference for the selection of HCFC-142b cracking catalyst and future research directions.
