Selective Production of Aromatics from 2-Octanol on Zinc Ion-Exchanged MFI Zeolite Catalysts
The aromatization of 2-octanol derived from castor oil as a byproduct in the formation of sebacic acid was investigated on various zeolite catalysts. Zn ion-exchanged MFI (ZSM-5) zeolites with small silica/alumina ratios and zinc contents of 0.5 to 2.0 wt. % were determined to exhibit good and stable activity for the reaction at 623 to 823 K. The yield of aromatics was 62% at 773 K and the spac...
متن کاملSynthesis of N-Formylation of Amines using Various Ion Exchanged Forms of Zeolite-A as Catalysts
Formamides represent an important class of intermediates in various organic syntheses. They have been used in the synthesis of some pharmaceutically important compounds such as Fluoroquinolones [1], 1, 2 dihydro quinolones [2] and Nitrogen based heterocyclic compounds [3]. In Lewis bases, its main importance is to catalyze some important reactions such as allylation [4] and hydrosilyation of ca...
متن کاملIdentification of two types of exchangeable sites for monovalent copper ions exchanged in MFI-type zeolite.
Three different approaches have been used to characterize the state of exchanged copper ions in copper-ion-exchanged MFI (CuMFI) samples. (1) Two types of an ion-exchangeable site with different adsorption properties for N(2) or CO molecules were identified depending on the pre-treatment temperature (723 or 873 K) of a sample prepared by using an aqueous solution of CuCl(2). (2) The state of th...
متن کاملBayberry-like ZnO/MFI zeolite as high performance methanol-to-aromatics catalyst.
Unique bayberry-like MFI zeolites are synthesized through a quasi-solid-state crystallization approach. This hierarchical zeolite structure has a relatively thick shell, densely grown nanocrystals with an ordered packed channel, high mechanical stability, high surface area and a low Si/Al ratio. Its catalytic efficiency for methanol-to-aromatics is significantly higher than that of conventional...
متن کاملCatalytic pyrolysis of waste rice husk over mesoporous materials
Catalytic fast pyrolysis of waste rice husk was carried out using pyrolysis-gas chromatography/mass spectrometry [Py-GC/MS]. Meso-MFI zeolite [Meso-MFI] was used as the catalyst. In addition, a 0.5-wt.% platinum [Pt] was ion-exchanged into Meso-MFI to examine the effect of Pt addition. Using a catalytic upgrading method, the activities of the catalysts were evaluated in terms of product composi...
