摘要
总结分析了近年来文献和专利,将HFCs的处理与转化方法分析归纳为消除处理与资源化转化利用2大类,其中消除处理方法有氧化燃烧法、等离子法、催化水解法,资源化转化利用方法有高温裂解转化烯烃法、共裂解法、催化脱氟化氢法。介绍了2大类、6种处理与转化方法,并分析了不同的HFCs处理与转化方法的利弊与工业应用前景。认为HFCs类物质可以转化为附加值高、环境友好的含氟烯烃、含氟聚合物和碘氟烃等,是未来HFCs的资源化转化利用的意义所在;而催化脱HF反应路线的技术关键问题是高效催化剂的开发。
In this paper,the literature and patent published in recent years were summarized,and the treatment and transformation of HFCs were analyzed and summarized into two categories:elimination process and resource utilization.The elimination methods were oxidative combustion,plasma method and catalytic hydrolysis.The resource utilization were high temperature cracking into olefins,cocracking method and catalytic dehydrofluorination.Through the detailed introduction of the above two categories with six methods,and analyzed the advantages and disadvantages and industrial application prospect of different treatment and transformation methods of HFCs,concluded that:HFCs could convert to fluorinated olefin,fluorinated polymer and fluorinated iodine hydrocarbon which had high value-added and friendly environment,which was the significance of resource utilization of HFCs in the future,and the key technical problem of HF catalytic dehydrofluorination was the development of high efficient catalyst.
