Wood activated carbon 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, Wood activated carbon Direct selling 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.

Wood activated carbon major 1. From the composition of both, carbon molecular sieve is an excellent non-polar carbon material, while zeolite molecular sieve is a hydrate of crystalline aluminosilicate metal salt. The two are completely different in the periodic table of chemical elements! 2. With different pore sizes, the pore composition of zeolite molecular sieves is obviously registered, which can be generally divided into macropores, mesopores and micropores, and there are interconnections between the pores, while carbon molecular sieves are generally micropores! 3. The adsorption principle is different. Zeolite molecular sieves absorb molecules of certain size and repel molecules of larger substances. Wood activated carbon Beijing Carbon molecular sieve contains a large number of micropores, which can effectively separate the components of gas mixture. 4. The uses are also different. Carbon molecular sieves are widely used in coal fields, petroleum, chemicals, metal heat treatment, electronic manufacturing, food preservation and other industries, while zeolite molecular sieves can be used in addition to petroleum, chemicals, natural gas, electronic production, industrial gas separation, pharmaceutical industry, refrigeration industry, and hollow glass manufacturing.

Wood activated carbon major 1. Strong adsorption selectivity: molecular sieve materials with different properties and pore sizes are configured for the product according to the different components of organic waste gas, so as to achieve targeted and selective treatment of organic waste gas, meet the design requirements and meet the emission standards. 2. Strong adsorption capacity: even if the gas composition concentration is very low at the mg level, it still has the adsorption capacity. The efficiency is 50% higher than that of similar activated carbon. 3. Wide adaptability of adsorption temperature: at a higher temperature, it still has a large adsorption capacity, while other adsorbents are greatly affected by temperature, so under the same temperature, the adsorption capacity of molecular sieve is large. Honeycomb zeolite molecular sieve is an efficient molecular sieve carrier with good adsorption performance, no secondary pollution and high temperature regeneration. It is widely used in the fields of adsorption, separation, catalysis and environment, and is more suitable for the treatment of organic waste gas with large air volume and low concentration. Wood activated carbon Beijing It is widely used in the production of basic organic chemical industry and petrochemical industry, as well as in the treatment of harmful gases, SO2 NOx、CO、CO2,NH3,CCl4、 Purification of water vapor and gaseous hydrocarbon waste gas

Wood activated carbon major Because the silicon (aluminum) oxygen tetrahedron of natural zeolite crystal has many holes and channels, which occupy cations and water molecules. When some other goods are completely dehydrated after baking, the crystal skeleton is not damaged, but forms large holes on the inner surface, which can absorb and store a large number of molecules, so it has the characteristics of large adsorption capacity and high selectivity. 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. Wood activated carbon Direct selling In different zeolite minerals, the proportion of silicon and aluminum is different, and the different proportion will cause some characteristics of zeolite changes, such as ion exchange and acid resistance.

Good regeneration temperature resistance: the concentration ratio of pollutants after adsorption and concentration by molecular sieve can reach 15 to 20 times, and the concentrated waste gas can be condensed and recovered or burned at high temperature as required 5. High strength: Wood activated carbon Direct selling Products coming to the company use special framework materials to make the positive pressure strength of honeycomb zeolite reach more than 3Mpa, which can reduce damage during transportation and installation.

The main components of zeolite are: silicon and aluminum, which have adsorption capacity and can be used as adsorbent; Zeolite runner is to use the specific pore size of zeolite to have the ability of adsorption and desorption for organic pollutants, so that VOCs waste gas with low concentration and large air volume can be concentrated and converted into low air volume and high concentration gas by the zeolite runner, which can reduce the operating cost of the back-end final treatment equipment. Wood activated carbon Beijing The characteristics of the device are suitable for treating waste gas with large flow, low concentration and various organic components. The disadvantage is high initial investment. The zeolite wheel adsorption purification device is a gas purification device that can continuously perform adsorption and desorption operations. The two sides of the zeolite runner are divided into three areas by special sealing devices: adsorption area, desorption (regeneration) area and cooling area. Wood activated carbon major The working process of the system is as follows: the zeolite runner rotates continuously at a low speed and circulates through the adsorption area, desorption (regeneration) area and cooling area; When the exhaust gas with low concentration and large air volume continuously passes through the adsorption area of the runner, VOCs in the exhaust gas are adsorbed by the zeolite of the runner, and the gas purified by adsorption is directly discharged; The organic solvent adsorbed by the wheel is sent to the desorption (regeneration) area with the rotation of the runner, and then the small amount of hot air continuously passes through the desorption area. The VOCs adsorbed on the runner are thermally desorbed in the desorption area to achieve regeneration, and the VOCs waste gas is discharged together with the hot air; After the runner is transferred to the cooling area for cooling, the adsorption can be carried out again. With the continuous rotation of the runner, the adsorption, desorption and cooling cycles are carried out to ensure the continuous and stable operation of waste gas treatment.
