Abstract
A method for improving the stability of a catalyst in recycling HFC-23 is provided. The recycling is realized by means of a fluorine-chlorine exchange reaction with HFC-23 and a halogenated hydrocarbon. The catalyst for the fluorine-chlorine exchange reaction comprises a main body catalyst and a metal oxide, wherein the metal oxide is selected from at least one metal oxide of K, Na, Fe, Co, Cu, Ni, Zn or Ti, and has an addition amount of 0.1-5 wt %. The method has advantages such as a good catalyst stability, a long life, and a low content of by-product CFC-12.
