Because the aluminum oxide tetrahedron of zeolite has a negative charge, and the skeleton hole contains cations, a strong electric field is formed around the cations. Therefore, the adsorption force of zeolite not only has a strong dispersion force, but also has a large electrostatic force. It is precisely because of this electrostatic relationship that zeolites have preferential selective adsorption on polar, unsaturated and polarizable molecules. It can strongly adsorb molecules containing polar groups such as hydroxyl ion, ammonium ion and other polarizable groups, especially water, which can form hydrogen bonds with aluminum silicon skeleton, so zeolite has strong water absorption. It can still adsorb even under low relative humidity and concentration, and its water absorption is higher than that of silica gel and activated alumina. Zeolite honeycomb molecular sieve The main material of 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 kind of material with good adsorption performance and 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.
