摘要

Catalyst for hydrogen chloride oxidation supported on Y zeolite with active ingredient of copper and assistant of rare earth oxide mixture and potassium was prepared. Effects of the catalyst size, the volume ratio of HCl to O₂ and reaction temperature on the oxidation of hydrogen chloride were investigated, and catalyst life for hydrogen chloride oxidation was studied. Results showed that 86% conversion of HCl was still obtained per pass at 490 (L-HCl)/(kg-cat·h) with the suitable catalystsize of 0.6 mm, 1.5 volume ratio of HCl to O₂ and 365°C reaction temperature. ICP analysis of copper content in condensate water from oxidation reaction showed that loss rate of the main active constituent of copper was 6 × 10^-6 g/h and the catalyst was good stability.
