Zeolite honeycomb molecular sieve In addition to physical adsorption, chemical reaction also often occurs on the surface of zeolite, which contains a small amount of chemical combination, oxygen and hydrogen in the form of functional groups. These surfaces contain oxides or complexes that can react with the adsorbed substances, so that they can combine with the adsorbed substances and aggregate to the interior and surface of zeolite. The main material of zeolite honeycomb molecular sieve adsorbent is natural zeolite. The zeolite manufacturer 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, non flammability, good thermal stability and hydrothermal stability. It is a good adsorbent with 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.
