Main Features:
1. Strong adsorption selectivity: This is because the pore size of the molecular sieve is neat and uniform, and it is also an ionic adsorbent. Therefore, it can selectively adsorb according to the size and polarity of the molecule. If it can effectively remove ethylene from saturated hydrocarbons, it can also effectively remove acetylene from ethylene, which is determined by its strong polarity.
2. Strong adsorption capacity. Even if the composition of the gas is very low, it still has the adsorption capacity.
3. There is still a large adsorption capacity at higher temperatures, while other adsorbents are greatly affected by temperature, so the adsorption capacity of the molecular sieve is large under the same temperature conditions. Because of the above advantages, molecular sieves have become a very good adsorbent, widely used in the production of basic organic chemicals and petrochemicals. They are also commonly used in the treatment of harmful gases, SO2, NOx, CO, CO2, NH3, CCl4. , purification of water vapor and gaseous hydrocarbon waste gas;
4, high temperature regeneration, high regeneration efficiency and high safety.
The use of shaped molecular sieves as adsorbents for exhaust gas treatment will become mainstream. The process of using molecular sieves as a carrier has been widely used abroad. The molecular sieve can be designed and applied according to the concentration of the pollutants and the particle size. After the molecular sieve adsorption and concentration, the concentration of the pollutants can be several times to several tens of times. The concentrated exhaust gas can be condensed and recovered or burned as needed.
