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.
Abstract
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 cata-lyst,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.
