Disproportionation of Ethylbenzene over Sapo-40
SAPO-40, a silicoaluminophosphate with a structure not topologically related with any aluminosilicate zeolite, was synthesised for the first time in 1984 by Lok and co-workers [1]. Recently, a synthesis procedure leading to pure SAPO40 was developed and the structure of this material was established by crystallographic methods. The framework topology (designated AFR by the International Zeolite...
متن کاملOptimizing the crystallinity and acidity of H-SAPO-34 by fluoride for synthesizing Cu/SAPO-34 NH3-SCR catalyst.
A series of H-SAPO-34 zeolites were synthesized by a hydrothermal method in fluoride media. The as-synthesized H-SAPO-34 zeolites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 physisorption, temperature-programmed desorption of NH3 (NH3-TPD) and nuclear magnetic resonance (NMR) measurements. The results showed that a certain concentration of F(-) anions p...

متن کاملSynthesis of SAPO-34 catalysts via controlled crystal growth
Introduction SAPO-34 is a silicoaluminophosphate zeolite with 8-membered ring windows (~0.38nm) displaying chabazite structure. SAPO-34 is an efficient catalyst showing improved catalytic performance in reactions such as methanol conversion to olefins [1], oxidative dehydrogenation of propane [2], conversion of light alkenes [3]. Its catalytic properties are mainly attributed to its mild acidit...
متن کاملPostural Assessment Software (PAS/SAPO): Validation and Reliabiliy
OBJECTIVE This study was designed to estimate the accuracy of the postural assessment software (PAS/SAPO) for measurement of corporal angles and distances as well as the inter- and intra-rater reliabilities. INTRODUCTION Postural assessment software was developed as a subsidiary tool for postural assessment. It is easy to use and available in the public domain. Nonetheless, validation studies...
