Activated Carbon Catalytic Combustion System

• The waste gas treatment process is currently UV photolysis + activated carbon adsorption, but the treatment efficiency is low.

• Use activated carbon adsorption concentration + CO catalytic combustion (or RCO regenerative catalytic combustion) to treat VOC organic waste gas

• Brief Introduction of Active Adsorption and Catalytic Combustion Desorption Regeneration Technology

Using the microporous adsorption characteristics of honeycomb activated carbon to adsorb organic waste gas is one of the most effective industrial treatment methods. Honeycomb activated carbon has the advantages of stable performance, corrosion resistance and resistance to high-speed airflow impact. Using it to adsorb organic waste gas can make the purification efficiency as high as 90-95%. After the honeycomb activated carbon is saturated with adsorption, it can be desorbed and regenerated by hot air. After regeneration, the activated carbon is put back into use. By controlling the flow rate of the desorption process, the concentration of organic waste gas can be concentrated 10-20 times. The desorption gas flow is heated to about 300°C by the burner device passing through the catalytic bed and ignited under the action of the catalyst. The purification efficiency of the catalytic combustion process can reach more than 97%, and CO2 and H2O are generated after combustion.

• The treatment efficiency is relatively high, with VOC treatment efficiency exceeding 80%;
• Activated carbon can be desorbed and regenerated and reused for 1 to 2 years, saving the cost of purchasing adsorption materials, hazardous waste treatment costs and labor costs;
• Catalytic decomposition has no flame combustion, low temperature requirements and relatively low operating energy consumption.
