摘要： Methods for purification of a fluorocarbon or hydrofluorocarbon containing at least one undesired halocarbon impurities comprise flowing the fluorocarbon or hydrofluorocarbon through at least one adsorbent beds to selectively adsorb the at least one undesired halocarbon impurities through physical adsorption and/or chemical adsorption, wherein the at least one adsorbent beds contain a metal oxide supported on an adsorbent in an inert atmosphere.
