Shanghai Co. --4A new molecular sieve sieve DME conversion rate of more than 50% of the basic Linghai zeolite, selectivity is relatively high [6-8]. However, a one-dimensional pore mordenite molecular sieve stacking fault prone zeolite, channel-shaped straight easy escape of reaction product, prolonged contact time of the reactants and the active surface Pulandian molecular sieve, or easy to form a large number of small molecules and cause blockage coke Kongdao Feng City zeolite, thereby reducing the impact of the diffusion performance oxonation activity and stability. Therefore, this study by X-ray diffraction (XRD), low temperature nitrogen adsorption (BET), pyridine adsorption infrared spectroscopy (Py-IR) to characterize studied by means of BEA / MOR 2 with co-crystallized phase crystalline molecular sieve and surface texture structure and acidic nature Shanghai Co., Ltd. of new molecular sieve zeolite - l Easy to use, the device is compact structure, small footprint, the overall skid; installation process is simple, no infrastructure put in place, connect the water, electricity, access to the trachea can be put into normal production. l high security, low decomposition pressure is 0.05Mpa; that is, with decomposition, are free to fluctuate within the range of rated gas with air, under normal circumstances without hydrogen storage tank; oxygen-free hydrogen production, hydrogen production are the whole process oxygen-free environment. 4) Applications: Wafangdian molecular sieve _ new molecular sieves (certified) _ new zeolite molecular sieves by the 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.
