Honeycomb zeolite molecular sieve high quality 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. Honeycomb zeolite molecular sieve Nanchang The main material of honeycomb zeolite adsorbent is natural zeolite.

Honeycomb zeolite molecular sieve Nanchang 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.

Molecular sieve has clear pore cavity distribution, extremely high internal surface area (600m2/s), good thermal stability (1000 ℃), and adjustable acid site center. The acidity of molecular sieve mainly comes from three coordinated aluminum atoms and aluminum ions (AlO)+on the framework and in the pores. OH based acid sensitive site center on molecular sieve HY obtained by ion exchange, Honeycomb zeolite molecular sieve Nanchang The aluminum ions outside the framework will strengthen the acid site and form the L acid site center. Polyvalent cations such as Ca2+, Mg2+and La3+can show the acid site center after exchange. The reduction of transition metal ions such as Cu2+and Ag+can also form acid site centers. In general, the higher the Al/Si ratio, the higher the specific activity of OH group. The modification of zeolite acidity can introduce protons through direct exchange of dilute hydrochloric acid. This method often leads to dealumination of molecular sieve framework. So NaY will become NH4Y and then HY. Because there are uniform small internal pores in the molecular sieve structure, when the molecular linearity of reactants and products is close to the pore size of the crystal, the selectivity of the catalytic reaction often depends on the corresponding size of the molecule and pore size. Honeycomb zeolite molecular sieve high quality This selectivity is called shape selective catalysis. There are two mechanisms leading to shape selectivity. One is caused by the difference of diffusion coefficient of molecules participating in the reaction in the pore cavity, which is called mass transfer selectivity; The other is caused by the space limitation of the transition state of the catalytic reaction, which is called transition state selectivity.

Honeycomb zeolite molecular sieve high quality The evaluation of the adsorption of zeolite depends not only on whether the specific surface area of zeolite is large enough, but also on whether the equipment is hydrophobic. When purchasing, people can choose the inspection equipment. When the air humidity for the hydrophobicity of the inspection equipment is greater than 60%, if the equipment is blocked and the machine works abnormally, people should carefully consider whether to purchase the equipment. It is important to know that the adsorption and hydrophobicity of the zeolite runner are equally important. The zeolite content of the zeolite runner is proportional to the adsorption concentration efficiency. Therefore, many people should pay more attention to whether the zeolite content of the equipment meets the requirements or is high enough when choosing to purchase the zeolite runner. On the one hand, selecting excellent equipment is also to enhance the potential value of the enterprise. Honeycomb zeolite molecular sieve Nanchang The adsorption and concentration technology of zeolite runner is deeply loved by enterprises because of its high efficiency and energy saving characteristics.
