Pore-expanded mesoporous MCM-41 silica-supported chromium oxide catalysts with different chromia loadings were synthesized using three different methods. The catalysts were thoroughly characterized and used for ethane dehydrogenation (DH). Reaction s

Pore-expanded MCM-41 silica was prepared in two steps, namely synthesis of MCM-41 in the presence of cetyltrimethylammonium bromide (CTAB) at 100 °C followed by a hydrothermal pore expansion treatment in the presence of dimethyldecylamine (DMDA) at

The best composition for achieving maximum propene yields during the propane ODH reaction over supported V 2 O 5 –MoO 3 /TiO 2 (VMoTi) catalysts were determined by applying statistical methodologies. Catalyst characterizations revealed that noninte

The kinetics of ethane and propane oxidation reactions over bulk V 2 O 5 suggests that the sum of the pre-exponential factors for alkene formation and direct alkane oxidation to CO 2 is closely related to the alkane oxidation activity. Furthermore, t

The effect of surface metal oxide loading and specific surface metal oxide species on the kinetic parameters associated with the propane oxidative dehydrogenation reaction is analyzed for several supported V2O5/Al2O3 (VAl) and MoO3/Al2O3 (MoAl) catal

Kinetic parameters are estimated for a sequential Mars van Krevelan (MVK) reaction model occurring over several supported vanadium oxide (vanadia) catalysts involved in the propane oxidative dehydrogenation (ODH) reaction. The estimated kinetic param

The steady flow of non-Newtonian polymer solutions on their own and together with air transverse to a bundle of circular rods, has been studied experimentally. In particular, the frictional pressure drop has been measured as a function of non-Newtoni

The molecular structures, oxidation states, and reactivity of 3 and 6% CrO3/ZrO2 catalysts prepared by incipient wetness impregnation were examined under different conditions. The in situ Raman spectroscopic studies under dehydrated conditions reveal
