Abstract

The invention provides an application of a general formula AM<2>O<5-x> compound as a catalyst for catalyzing VOC combustion. The general formula AM<2>O<5-x> compound is a mullite-type composite oxide,wherein A is any one metal or more of lanthanide metal elements, Bi and Y, M is one or more of first transition series transition metal elements, and x is between 0 and 1. The general formula AM<2>O<5-x> compound has relatively good catalytic effects on VOC combustion. The AM<2>O<5-x> compound is the mullite-type composite oxide, binding energy between the components is relatively large, and thusstability of the compound for catalytic VOC combustion is relatively high, and a service life of the compound is relatively long. The AM<2>O<5-x> compound does not contain precious metals, and thus the cost is relatively low. At the same time, a preparation method of the compound is relatively mature and simple in the prior art, so that mass production can be carried out for large-scale VOC treatment; and further, after experimental verification, the compound is suitable for VOC treatment in different industries.

Description

Technical field

[0001] The present invention relates to the field of VOC processing, in particular to a general type AM 2 O 5-x The application of the compound as a catalyst for catalyzing the combustion of VOC. Background technique

[0002] Volatile Organic Compounds (Volatile Organic Compounds), referred to as VOC, usually refers to the general term for harmful volatile organic compounds, generally including hydrocarbons (alkanes, alkenes, alkynes, cyclic hydrocarbons), aromatics, ketones, esters, Alcohols, ethers, aldehydes, acids, amines, nitriles, epoxy compounds, chlorides, etc.

[0003] VOC is the formation of fine particulate matter (PM2.5) and ozone (O 3 Compared with the control of particulate matter, sulfur dioxide, and nitrogen oxide pollution, my country’s VOC management foundation is weak and has become a shortcoming of atmospheric environmental management. At present, petrochemical, automotive, electronics, chemical, industrial coating, packaging and printing, oil s...
