Project Introduction:

The direct emission of high-concentration volatile organic compounds (VOCs) in industrial exhaust gas is one of the important sources of air pollution. Catalytic oxidation technology is considered to be the most promising VOCs due to its advantages such as strong processing capacity, low energy consumption, and low secondary pollution. The core of purification technology lies in the use of high-performance catalytic materials and new reaction equipment. In view of the current problems faced by high-concentration VOCs catalytic oxidation materials in industrial tail gas, such as high cost, easy loss of components, easy poisoning of catalysts, high price and large floor area of reaction equipment, we have carried out research on new catalysts based on supported precious metal nanomaterials with high dispersion, low load, anti-poisoning, and renewable properties. In view of the characteristics of small enterprises, imperfect ventilation equipment, and mostly scattered emissions of VOCs, channel micro-reaction equipment has been developed. In order to achieve equipment integration and low cost.

Technical advantages:

Through the optimization of this technology, the operation platform of channel-type VOCs catalytic oxidation reaction equipment has been completed in the laboratory, and its catalytic oxidation ability for "triphenyl", alcohols, ethers, esters and other compounds has been initially investigated. Compared with traditional fixed-bed reaction equipment, this equipment has the advantages of small area, high purification efficiency, and high reaction heat utilization. It can meet the VOCs purification needs of small and medium-sized enterprises and has good application prospects.
