Special activated carbon for catalyst carrier major Due to its large pore size, mesoporous materials have become a good carrier for molecular reaction with large size. However, the pore wall of mesoporous materials is amorphous, so their hydrothermal stability and thermal stability cannot meet the harsh conditions required for petrochemical applications. Because there are metal ions with low electricity price and large ion radius and water in the combined state, water molecules are continuously lost after heating, but the crystal skeleton structure remains unchanged, forming many cavities with the same size. The cavities are connected by many micropores with the same diameter. These tiny holes have uniform diameters, which can adsorb molecules smaller than the diameter of the hole into the interior of the hole, By excluding molecules larger than pores, molecules with different shapes, diameters, polarities, boiling points and saturation levels can be separated, Special activated carbon for catalyst carrier manufactor It has the function of "screening" molecules, so it is called molecular sieve. At present, molecular sieves are widely used in metallurgy, chemical industry, electronics, petrochemical industry, natural gas and other industries.

Zeolite molecular sieves have the following potential applications. Special activated carbon for catalyst carrier manufactor (1) Due to the high whiteness of molecular sieves, the optical properties of paper can be improved. (2) It can improve the loose thickness and printability of the paper. (3) Molecular sieves can be used to prepare special papers such as gas filter paper, rust proof paper and photocatalysis paper due to their open structure. (4) It can be used for low weight newsprint and book paper, and can effectively avoid ink penetration. (5) Its ion exchange performance can avoid resin and filler deposition. Special activated carbon for catalyst carrier major (6) It can be used for phenolic paper laminate to improve its corrosion resistance in humid environment. Phenolic paper laminates used as insulators in printed circuit boards and integrated circuits will be affected by electrolytic corrosion when exposed to high humidity. (7) It is mixed with titanium dioxide (TiO2) filler to produce high-quality white paper.

Special activated carbon for catalyst carrier major There are cavities and channels in the crystal structure of zeolite with large adsorption capacity, whose volume accounts for more than 50% of the total volume of zeolite crystals. Moreover, the micropores of zeolite are evenly distributed, and the pore size is small, which is equivalent to the molecular size of general substances. The internal surface area of zeolite crystals can reach more than 1000 square meters. Therefore, the adsorption capacity of zeolite is particularly large. The main material of honeycomb zeolite adsorbent is natural zeolite. The manufacturer of zeolite is composed of silica Inorganic microporous material composed of al_2o_3 and alkaline metal or alkaline earth metal, with inner pore volume accounting for 40-50% of the total volume and specific surface area of 100-500 m2/g, is characterized by high temperature resistance, non flammability, good thermal stability and hydrothermal stability. It is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution, and can be regenerated at high temperature. Compared with honeycomb activated carbon, its performance is about 25% of its efficiency, However, 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.

Special activated carbon for catalyst carrier Shandong 】Zeolite adsorbent has outstanding advantages 1. Strong adsorption selectivity. The pore size of molecular sieve is uniform, and it is also an ionic adsorbent. Therefore, it can selectively adsorb according to the size and polarity of molecules. It can effectively remove ethylene, propylene and acetylene from saturated hydrocarbons, which is determined by its strong polarity. 2. Strong adsorption capacity. Even if the composition concentration of the gas is very low, it still has the adsorption capacity of. 3. It is less affected by temperature. At a higher temperature, it still has a greater adsorption capacity, while other adsorbents are greatly affected by temperature, so at the same temperature, the adsorption capacity of zeolite molecular sieve is large. 4. It can be regenerated at high temperature, with high regeneration efficiency and high safety. 5. Strong resistance to poisoning and good thermal stability. Zeolite molecular sieve is an excellent adsorbent, Special activated carbon for catalyst carrier major It is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases nox、co、co2，nh3，ccl4、 Purification of 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.
