Title:
CATALYST FOR PREPARING CHLORINE BY HYDROGEN CHLORIDE OXIDATION, AND PREPARATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/023717
Kind Code:
A1
Abstract:
A catalyst for preparing chlorine 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 a fluidised bed reactor, the present catalyst can achieve a one-way hydrogen chloride conversion rate of 80 to 85%. Almost all of the 0-1000 mg/kg of chlorobenzene contained in hydrogen chloride gas can be converted into CO2 and H2O without generating polychlorinated benzene.
