Kinetic, spectroscopic, and chemical titration data indicate that differences in monomolecular isobutane cracking and dehydrogenation and methanol dehydration turnover rates (per H) among FAU zeolites treated thermally with steam (H-USY) and then chemically with ammonium hexafluorosilicate (CDHUSY) predominantly reflect differences in the size and solvating properties of their supercage voids r...

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...

Nonoxidative dehydrogenation of isobutane is one the sustainable strategies for producing high value added isobutene. As alternatives commercial Pt- and Cr-based catalysts, supported V-based catalysts are worthy study. In this work, a series VOx/mMgAlO-R (m = 10, 15, 20, 25 30) were designed prepared by loading VOx on mMgAlO composite oxide supports derived from mesoporous Al2O3-supported layer...
