Shanghai there are new molecular sieve Ltd. Abstract: BEA / MOR Zeolites and pure phase by X-ray diffraction, inductively coupled plasma, isothermal adsorption, pyridine adsorption infrared spectroscopy and thermal losses BEIPIAO zeolite characterization, and its DME carbonylation of methyl acetate reaction performance evaluation and comparison. The results show large stone sieve, with a total of 2 crystalline molecular sieve different from BEA and MOR Lingyuan zeolite crystal structure, specific surface area and average pore size is between two pure phase, Ltd. Shanghai new molecular sieve zeolite heat treatment of metals: stainless steel belt, precision steel, steel and other steel and alloys, brass, copper, copper and other metal reduction annealing atmosphere: tungsten and molybdenum reduction, reducing atmosphere reducing iron metallurgy: iron, copper reduction reducing protective atmosphere Other: magnetic materials, special ceramics, diamond products, hard alloy shielding gas. V. After the atmosphere of the treatment of AQ FC decomposition Remarks purified gas composition 75% H2, 25% N2 75% H2, 25% N2 gas index increased oxygen impurity oxygen ≤3ppm ≤3ppm to 1ppm residual ammonia may be ≤500ppm ≤2ppm to ≤1ppm working pressure 0.05Mpa Gaizhou molecular sieves, there is a new molecular sieves (certified), there is a new molecular sieve zeolite from Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is Shanghai's Songjiang District, elemental leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. There are new leaders in the molecular sieve with the staff warmly welcome all inquiries negotiations to create new molecular sieves better future.
