Abstract

A catalyst for the catalytic combustion of combustible waste gas is prepared by dipping the Pt as active component on the coated layer of cellular ceramics as carrier. The said coated layer contains Al2O3 (20-80 wt.%), TiO2 (10-40 wt.%), CeO2 (5-30 wt.%) and ZrO2 (5-20 wt.%). Its advantages are high utilization rate of Pt, and high distribution uniformity.

Description

1. Technical field

[0001] The invention relates to a catalytic combustion catalyst and a preparation method thereof, more specifically, the invention relates to a honeycomb catalytic combustion catalyst for purifying and treating organic waste gas and other waste gases containing combustible components and a preparation method thereof. 2. Technical background

[0002] Many industrial enterprises emit a large amount of organic waste gas. This problem is particularly prominent in petroleum refining and chemical industries, as well as in industries such as electronics, printing, coatings, shoemaking, enameled wire processing, and food and feed processing. The discharge of organic waste gas has seriously polluted the atmosphere and caused great harm to the human body, so it has attracted widespread attention. Among the purification and treatment methods of organic waste gas, catalytic combustion technology is particularly attractive. Catalytic combusti...
