The effect of Ga, V, and Zr content on the structural properties catalytic behavior H-ZSM-5 monolithic catalysts-supported gallium oxide, vanadium zirconium oxide in oxidative dehydrogenation propane (ODHP) have been investigated a continuous tubular microreactor using CO2 as mild oxidant. SEM-EDX confirmed homogeneous distribution metal oxides within printed oxide/H-ZSM-5 catalysts ODHP reacti...

‘H magic angle spinning nuclear magnetic resonance (MAS NMR) measurements on ZSM-5 synthesized with tetrapropylammonium ions as structure-directing template, calcined and hydrogen exchanged, indicate high concentrations of silanol groups (up to 4.6~ 10zo SiOH g-‘)_ ‘H NMR, “Na and % MAS NMR studies of zeolites ZSM-5 with different Si/Al ratios support a model which attributes the majority of th...

In this study, hierarchical H-ZSM-5 zeolite is prepared via post-synthetic modification of parent H-ZSM-5 zeolite (Si/Al=35) synthesized from bagasse (BGA) as silica source using desilication with alkaline treatment (AT). For optimizing the effective parameters on desilication, Taguchi method was utilized. Cultivated BGA in the south of the Caspian Sea (Mazandaran province, Iran) is applied for...

Mesoporous ZSM-5 prepared by alkaline treatment was demonstrated as an efficient catalyst for the cellulose hydrolysis in ionic liquid (IL), affording a high yield of reducing sugar. It was demonstrated that mesoporous ZSM-5 (SiO₂/Al₂O₃ = 38) had 76.2% cellulose conversion and 49.6% yield of total reducing sugar (TRS). In comparison, the conventional ZSM-5 had a mere 41.3% cellulose conversion ...

The product distribution of methanol to hydrocarbons conversion over SAPO-34 and ZSM-5 catalysts was studied using thermodynamic equilibrium and Anderson-Schulz-Flory (ASF) distributions. The equilibrium compositions were calculated using constrained Gibbs free energy minimization. The effect of catalyst type was considered by setting upper limits to product carbon number due to sh...
