Inert gas purification catalyst, raw material composition and preparation method

The present invention discloses an inert gas purification catalyst, a raw material composition and a preparation method, the inert gas purification catalyst comprises active components, an auxiliary agent, a carrier and a binder, each active component comprises an oxide of Ni, an oxide of V and an oxide of Zn, wherein the auxiliary agent comprises one or a mixture of more than two of a Cr compound, a P compound and an As compound. Compared with the prior art, the invention has the advantages that the active components of the catalyst are reasonably selected and non-noble metal, production costis relatively low, deep removal of different impurity gases is facilitated, and the catalysts have large specific surface areas and are evenly distributed, the active components have small particlesand high activity so that use amount of the catalyst is reduced; and operation cost and the like are saved. The invention is not only suitable for hydrogen, oxygen, nitrogen, argon, helium, neon and other bulk gases, but also
