A catalyst for preparing chlorine gas by hydrogen chloride oxidation, comprising the following components calculated according to mass content based on the total weight of the catalyst: 0.5-20 wt % copper; 2-10 wt % manganese; 0.05-2 wt % boron; 0.01-3 wt % chromium; 0.1-10 wt % rare earth metal; 0.1-10 wt % potassium; and 3-15 wt % titanium; also comprising 0.02-1.1 wt % phosphorus; and 0.03-1.9 wt % iron; the carrier content is 55-90 wt %. In the case of a fluidized bed reactor, the present catalyst can achieve a one-way hydrogen chloride conversion rate of 80-85%. Almost all of the 0-1000 mg/kg of chlorinated benzene contained in hydrogen chloride gas can be converted into CO2 and H2O without generating polychlorinated benzene.
A catalyst for preparing chlorine gas by hydrogen chloride oxidation, wherein the catalyst comprises a copper element, a manganese element, a boron element, a chromium element, a rare earth element, a potassium element, a titanium element, a phosphorus element, an iron element and a carrier.
A preparation method for a catalyst for preparing chlorine gas by hydrogen chloride oxidation, wherein the method comprises the following steps:
