The actual application of zeolite adsorbent

Zeolite adsorbent embodiment of the utility model or the technical scheme, zeolite adsorbent for example below or the existing technical description of the need to usesimple introduction, obviously, zeolite adsorbentis only the utility model with some examples, for the power domain common technical personnel, in the premise of zeolite adsorbent do not pay a creative, emptying device zeolite adsorbent for PSA oxygen concentrator, zeolite molecular sieve desiccant and zeolite adsorbent comprises two adsorption towers two arranged at the lower end is connected with one end of the adsorption tower of the two electromagnetic valve are respectively used in pipeline. Natural gas drying of the two the electromagnetic valve is connected to the other end of the pipe is respectively for the adsorption tower; natural gas drying the vent ductconnected by pipeline are respectively connected to the vent valve vacuum pump end and - end; the other end of the vent valve and the other end of the vacuum pump is connected with the muffler through the technical scheme of the utility model,molecular sieve design gasdrying by adsorption vent tower in the add a vent valve, gas drying in equipment switching venting early, vent valve open , zeolite molecular sieve desiccant adsorption tower by the pressure difference between inside and outside of the internal exhaust gas vent part (about 70% of the total), zeolite molecular sieve desiccant residual gasin vacuum pump; gas drying reduces the vacuum pump load, zeolite molecular sieve desiccant for drying natural gas shortens working period of vacuum pump gas drying,prolong the service life of vacuum pump; design of the muffler to reduce workplacenoise, the effective protection of workers' hearing. The above is only preferred ventdevice of the utility model is a PSA oxygen machine implementation, it should be pointed out, gas drying of ordinary skill in the art, not from the creation of the utility model is the premise, gas drying can also make some deformation and improved,these all belong to the scope of protection of the utility model.

Application of the principle of a temperature swing adsorption gas dryer

Application of the principle of a temperature swing adsorption gas dryer, the partial pressure of water vapor at room temperature and a high adsorption (work); zeolite adsorbent  molecular sieve supplier  at a higher temperature, low water vapor partial pressure of parsing (regeneration). That adsorbent moisture adsorption in the adsorption process, the regeneration process again rely on high-quality effects angrily (dry air heating) thermal diffusion mechanism and can  molecular sieves msds  be completely removed. Heaters generally electric heater, heat or steam can also be used like a compressor.

The entire device consists of two parallel working drying tower and heaters, circulation fans, coolers, filter. In addition to drying tower, regeneration Taqie change requires manual operations, all the rest of the action automatically by the device can also be designed to be fully automated.

Surface roughness and zeolite having a porous structure

Surface roughness and zeolite having a porous structure, it has a strong carrying capacity, can only be uniformly adsorbed on the surface of the material, and can be adsorbed to the inner cavity and the channel, to improve the utilization of the material can  zeolite 5a  also greatly zeolite desiccant  improve the mixing of uniformity. Trace elements also can be extended release time is more conducive to animal absorption. In addition, the zeolite can request processing, 4a zeolite molecular sieves  and can choose between 30 mesh to 200 mesh. This offers a great selection of different materials to facilitate carrier and diluent specifications. Zeolite acid, bulk density of 1.2 ~ 1.4kg / liter, excluding oil and crude fiber nor static phenomenon, these characteristics are consistent with carriers and diluents should have the condition. Therefore, further research should be developed and utilized.

Zeolite molecular

It has the structure and characteristics of the crystal, the surface of a solid skeleton, the internal vpsa oxygen generator cavities of the adsorbed molecules may play a role. There are connections between each bore hole, the molecules through the pores. Due to the nature of the cavity clean, very uniform distribution of pore size molecular sieve. Zeolite crystals inside the cavity based on its size selective adsorption of molecules, ie molecules adsorbed molecules of a certain size to the exclusion of the larger 5a molecular sieves species. Zeolite molecular sieve pore or channel their system can be divided into the hole, the hole (mesoporous) and holes zeolite three groups. Pressure Swing Adsorption oxygen-enriched air can be used for separation.

molecular sieve grace

Zeolite is a natural zeolite powder molecular sieve grace ground from rock, the color is white. Can remove 95 percent of ammonia, water purification, to ease transfer water phenomenon.

Superficial knowledge of the porous molecular sieve material

Porous psa oxygen generator molecular sieve materials are an important class of inorganic non-metallic advanced materials in the fields of petrochemical, materials science, energy storage, environmental protection and management, bio-medicine, with a broad expansion of space and good prospects.  With the deepening of research work, according to the actual needs of human beings to design and synthesize more features excellent performance molecular sieve materials, as people's living standards improve, the development of human civilization and social progress, play an important role. 

 In recent years, our country has made significant progress in zeolite synthesis and preparation as well as the catalytic converter and other molecular sieve powder catalytic materials research by the national attention, since the "Plan", has won a major project of the National Natural Science Foundation, the National Climbing Program and the state's major Basic Science Program (973) and other project support, has made a series of major scientific and technological achievements.  Especially Zeolite synthesis of mesoporous materials research and other fields are at the international forefront.

Research on small grains ZSM-5 zeolite catalyst stability

 Small crystal molecular sieves 5a stability and its good resistance to carbon deposition capacity.
 Looking at the results from the test response analysis of methanol in different grain sizes of ZSM-5 zeolite on the conversion, the amount of coke ZSM-5 zeolite surface even a small amount of coke grains is higher than a large grain of ZSM-5 zeolites molecular sieve catalyst life of small grains larger than grains of zeolite long.
 This phenomenon is due to the small grain size of ZSM-5 zeolite with a large pore volume and appearance of the area and the outer surface of the acid sites and more features, large pore volume of the catalyst can effectively increase the ability of anti-deactivation, more external surface acid sites can during the reaction to ensure that there are more active center can be used; the contrary, the large grainsmolecular sieve powder with a small external surface area ratio of inner surface area and the average particle diameter is large, the molecular diffusion resistance is large, pores are formed in the macromolecular product is not easily diffuse out, thereby blocking pores, reducing the effective utilization of the acid center, to accelerate catalyst deactivation.
