molecular sieve activation

The molecular sieve activation adsorption or exclusive affected by molecular electrical function. Synthetic zeolite is according to the size of the molecules and polarity and the special function of selective adsorption, thus it can be to dry or purification of gas or liquid, this also is the basis of molecular sieve can be separated. Synthetic zeolite can meet the demand for adsorption and choose product features extensive industry, in industrial separation is also a large number of application to the synthesis of zeolite molecular sieves.
activated alumina water treatment has a great effect on catalytic science and technology. The invention of the '60 s molecular sieve cracking catalyst, triggered a technology revolution of oil refining industry. In the 70 s found that the shape-selective ZSM - 5 zeolite, makes the important petroleum refining and petrochemical industry a new industrial process (ethyl benzene, toluene disproportionation production, heavy oil dewaxing, etc.) development success. 80 s delay elements heteroatomic TS - 1 the double glazing desiccant molecular sieve catalytic oxidation "active field. In recent years, molecular sieve in "environmental catalytic application is also developing quickly. The successful application of molecular sieve in industrial catalysis process inspired molecular sieves synthesis, modification, characterization and application research of extensive. Molecular sieve modified the most basic way is through the secondary synthesis, impurity atoms with crystal to replace, change its skeleton. AEM for detection of nanoscale range of elements and their changes. Below by dealuminated Y zeolite molecular sieves and TS - 1 as an example, introduces the application of AEM in molecular sieves synthesis.
emergence of molecular sieve of
