TRED Series Molecular Sieve Properties
What is TRED Series Molecular Sieve ?

The crystal structure of the molecular sieve is composed of silicon, aluminum, sodium, and other elements, in which silicon and aluminum atoms form tetrahedral structures, and sodium atoms fill the gaps between these tetrahedral structures. Shared oxygen atoms connect these tetrahedral structures to form a regular arrangement of pore structures. These pores can be selectively adsorbed and separated according to the size and polarity of different molecules, so they are widely used in various fields. ED series molecular sieve is a kind of molecular sieve material with wide application prospects. It has a high specific surface area, activity, and selectivity and is widely used in catalysts, carriers, and auxiliaries. ED series molecular sieve can also be used as an efficient adsorbent and separation agent. Due to its high specific surface area, high activity, and high selectivity, it can efficiently adsorb and separate various mixtures of gases and liquids. For example, molecular sieves can be used for molecular adsorption and separation in natural gas purification and fuel oil desulfurization fields. In addition, molecular sieves can also be used in sewage treatment, desalination, and other environmental protection projects.

Applications of TRED Series Molecular Sieve:
Oil and Gas industry:
In the oil and gas industry, ED series molecular sieves can be used for enhanced oil recovery and natural gas purification. Its regularly arranged pore structure provides efficient and reversible molecular adsorption and separation properties. The acidic function of molecular sieves can be used to catalyze pyrolysis, alkylation, isomerization, and other reactions to improve oil and natural gas utilization efficiency. In addition, molecular sieves can also be used as catalyst carriers and catalyst additives to improve the activity and selectivity of the catalyst.
Chemical Industry:
In the chemical industry, ED series molecular sieves can be used in catalysts, catalyst carriers, and auxiliaries. The pore structure of a molecular sieve can provide efficient molecular adsorption and separation properties to promote the chemical reaction. In addition, the acidic function of molecular sieves can be used to catalyze esterification, polymerization, polycondensation, and other reactions.
Environmental protection:
In environmental protection, ED series molecular sieves can be used for air purification and waste gas treatment. It has the characteristics of high activity and high selectivity. It quickly adsorbs and segregates harmful gases like volatile organic compounds, nitrogen oxides, and pollutants such as soot and particulate matter. In addition, molecular sieves can also be used in sewage treatment, desalination, and other environmental protection projects.
Separation technology:
In separation technology, ED series molecular sieves can be used for gas, liquid, and solid separation. It has the characteristics of high selectivity and high permeability and can efficiently separate various gas and liquid mixtures, as well as solid mixtures. In addition, molecular sieves can also be used in chromatographic analysis, ion exchange, and other fields.
Material field:
ED series molecular sieves can be combined with other materials to form functional materials. For example, molecular sieves can be used as an additive or enhancer for ceramic materials, polymer materials, and metal materials to improve the performance and stability of materials. In addition, molecular sieves can also be used to manufacture catalyst carriers, filters, molecular sieve membranes, and other materials.

Production Method of TRED Series Molecular Sieve:
In the synthesis stage, the basic units of molecular sieves are prepared by hydrothermal synthesis, ion exchange, microemulsion, and other methods. The hydrothermal synthesis method is one of the most commonly used methods. The silicate aqueous and aluminum brine solutions are mixed, adding the appropriate template agent reaction under a certain temperature and pressure conditions for a certain time. Then, molecular sieve crystals are obtained after washing, separation, drying, and other treatments. The ion exchange method is to exchange the specific ion exchanger with the cation in the molecular sieve crystal to change the ion type and structure of the molecular sieve and prepare the molecular sieve with specific properties. The microemulsion method is to form a tiny emulsion, synthesize a molecular sieve in microemulsion drops, and then prepare a molecular sieve with specific structures and properties by controlling the synthesis conditions.
In the processing stage, the synthesized molecular sieve is separated, washed, dried, etc., to obtain qualified molecular sieve products. Generally, it uses filtration, centrifugal separation, washing, and other processes for processing. Filtration is the separation of molecular sieve crystals from the synthetic solution, which can be used by vacuum, pressure, and other methods. Washing is to wash out impurities and unreacted raw materials in molecular sieve crystals to improve the purity and stability of the molecular sieve. Drying is to dry the molecular sieve crystal after washing to remove the water and other volatile substances in it to get a dry molecular sieve product.
