Heavy oil hydrogenating treatment catalyst and preparation method thereof

Abstract

The invention discloses a hydrogen chloride oxidation catalyst which takes an ReY molecular sieve as a carrier, and copper, alkali metals and rare earth metals are loaded on the molecular sieve, wherein, the load of copper oxide on the molecular sieve is 0.1-30wt%, the load of alkali metal oxides is 0-5wt%, and the load of rare earth metal oxides is 0-10wt%. The invention further discloses a preparation method of the catalyst. The preparation method adopts a mixed rolling-extrusion molding method for preparing the catalyst. The preparation method of the catalyst is simple in operation, and the loss rate of the copper and other active components is low, therefore, the capacity of hydrogen chloride oxidation reaction on the catalyst is improved, the service life of the catalyst is prolonged, the catalyst cost is lowered, the generation of heavy metal ion waste water is avoided, and the purpose of clean production of the catalyst is achieved. The catalyst of the invention can be used for a long time, and the hydrogen chloride oxidation reaction can be carried out at lower temperature.
