Zeolite honeycomb molecular sieve It is a very excellent adsorbent, which is widely used in the production of basic organic chemical industry and petrochemical industry. In the treatment of harmful gases, it is also commonly used in the purification of so2, nox, co, co2, nh3, ccl4, water vapor and gaseous hydrocarbon waste gas; As well as air purification and deodorization in biochemical industry, paint industry, underground places, leather factories and animal breeding places; Adsorption of flue gas odor, removal of mercury vapor, etc. The main material of honeycomb zeolite adsorbent is natural zeolite. Zeolite honeycomb molecular sieve is an inorganic microporous material composed of sio2, al_2o_3 and alkaline metal or alkaline earth metal. Its inner pore volume accounts for 40-50% of the total volume, and its specific surface area is 100-500 m2/g. It has the characteristics of high temperature resistance, nonflammable, good thermal stability and hydrothermal stability. It is a kind of good adsorption performance, no secondary pollution High efficient molecular sieve carrier that can be regenerated at high temperature, compared with Honeycomb activated carbon Its performance is about 25% of its efficiency, but it is widely used in the fields of adsorption, separation, catalysis and environment due to its high temperature resistance and difficult ignition. It is more suitable for the treatment of organic waste gas with large air volume and low concentration.
