Molecular Sieve Co. Shanghai new Thomas et al use HRTEM technique was first discovered in 1982, ZSM-5 / ZSM-11 2-phase co-crystallization, now it has been reported synthesis of SSZ-26 / SSZ-33, ZSM-34 (OFF / ERI ), SSZ-36 (ITE / RTH), STF / SFF, SM-3, ZSM-20 and EMT / FAU and other two-phase co-crystalline molecular sieve [1-4]. Qi Xiaolan using fluoride -TEA composite template system, synthesized zeolite BEA - two-phase coexistence mordenite zeolite fields. Shanghai Co. --4A new molecular sieve sieve DME conversion rate in more than 50% of basic, relatively high selectivity [6-8]. However YONGJI zeolite, mordenite zeolite one-dimensional channel zeolite Yuci prone stacking fault, straight, tubular channel in the reaction product is not easy to escape zeolite, extending the contact time of the reactant molecules and the active surface, easy to form a large number of small molecule or cause coked zeolite Houma clogged pores, thus reducing the impact of the diffusion properties 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 the means to study the BEA / MOR 2 with co-crystallized zeolite crystal phase and surface texture characteristics structure and acidic nature, Houma sieve sieve _ _ new new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) strong, credible, in Shanghai's Songjiang District elemental industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the new molecular sieves, and you hand in hand into the brilliant, for a better future!
