selectivity (shape-)m-xylene isomerizationzeolites.A high-silica zeolite KZ-1 with two different SiO2/Al2O3 ratios has been synthesized hydrothermally. Its sorption behaviour suggests it to be a medium-pore zeolite with 10-membered ring pore openings. The acid form of the sample with SiO2/Al2...
SynthesisZSM type zeoliteKZ-1pyrrolidinefive-membered ringcrystallizationCrystallization of zeolites from the system pyrrolidine-Na 2O Al 2O 3 SiO 2 H 2O was investigated. Five zeolites, ZSM—5, ZSM—35, ZSM—39, ZSM—48 and KZ—1, were synthesized as single phases, whose crystallinity was ...
Birds were divided into four treatment diets (4 replicates of 7 birds each): K (control), KB (K+ 1% bentonite), KZ (K+ 1% zeolite), KBZ (K+ 1% Z+ 1% B). The birds were fed initially for two weeks a commercial starter ration and followed by treatment diets 15 to 42 days of ...
以WO3为探针,鉴定了不同催化剂的氢溢出能力,Rh@分子筛催化剂中氢溢出能力的顺序为S-1 < KZSM-5 < S-1-OH < HZSM-5,这与这些催化剂的选择性趋势非常吻合,氢溢出能力越强,甲烷产物越多。这一现象与通常认知非常吻合,即氢溢出导致形成高活性氢物种,有利于 CO/CO2深度加氢转化为甲烷,从而在 Rh@分子筛催化...

The potential map of the CH4-KZSM-5 system also exhibits a character similar to that around a large cation, although not so marked. Good agreement between the experimental heat of adsorption and the heat of adsorption calculated with the potential energy is obtained for every CH4-MeZSM-5 ...

Parker and Bibby describe the synthesis of KZ-1 in ZEOLITES 1983, 3, 8-11 from reactant compositions comprising pyrrolidine, dimethylamine or 2-aminopropane ranging from a SiO2/Al2O3ratio of from 55-110 to give a product with a particular XRD pattern and typically having a BET surface area...
The study published in the July 31, 2009 issue of "Science" periodical offers data on producing zeolite films for separation processes of gas, liquid, and vapor membranes. Michael Tsapatsis, chemical engineer at UMN, believes that the improved crystal bondings reduce the defects in zeolite ...
