A study of the formation of microporous material SAPO-37
The crystallizatio n of mic roporous material SAPO-37 was studied under hydrothermal synthesis (HTS) and dry gel conversion (DGC) conditions. The evolution of the intermediate phases as a function of crystallization time was followed by several techniques including PXRD , SEM, AFM, and solid-state NMR. For DGC, SAPO-37 crystallizes from a semi-crysta lline layered precursor containing large por...
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 کاملComputer Modelling of Microporous and Oxide Catalysts
Computer modelling provides a range of powerful tools for exploring catalytic processes at the molecular level. In particular, modelling allows detailed characterisation of active site structures and of reaction mechanisms; and the techniques are particularly powerful when used in conjunction with experimental investigations. We will illustrate the current state-of-the-art of this field by summ...
متن کاملCatalysts Facilitate Molecular Transformations
The efficient, economical conversion of fossil feedstocks requires improvements in the controlof the individual reactions, better management of hydrogen, and more selective removal ofheteroatoms. The challenges are increasing as feedstocks such as heavy oils, tar sands, shale,and coal become heavier. Progress requires the detailed understanding of the compositions ofthe feedstoc...
متن کاملTemplate control in ionothermal synthesis of aluminophosphate microporous materials.
Pentaerythritol/quaternary ammonium eutectic mixture as an ionic solvent: the quaternary ammonium cations can be easily controlled to exert their structure-directing effect in ionothermal synthesis of aluminophosphate microporous materials.
