Preparation and characterization of template-free mordenite type zeolite and comparison of m-xylene isomerization reaction over mordenite and SAPO-11
In this work, Mordenite zeolite was successfully synthesized with Si/Al ratio of 18 in absence of organic template. The hydrothermal method was applied for synthesis under optimum conditions: 24 h synthesis time, 180°C temperature and 2 days aging time. The obtained zeolite was characterized by X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray fluorescence (XRF), Fourier Trans...

متن کاملEffect of solvation and confinement on the trans-gauche isomerization reaction in n-butane.
The effect of solvation and confinement on the conformational equilibria and kinetics of n-butane is examined using molecular dynamics simulations of the bulk and confined fluids and compared to appropriately chosen reference states. Clear evidence for a solvent shift of the preferred conformation in bulk n-butane is found. At a temperature of 292 K and a density of 6.05 nm-3 a small solvent sh...
متن کاملPlatinum- and iron-doubly promoted tungstated zirconia catalyst for n-butane isomerization reaction
The catalysis of n-butane isomerization over iron-promoted tungstated zirconia (F1.2WZ) and platinum–iron-promoted tungstated zirconia (P/F1.2WZ) catalysts was studied and correlated to the catalyst characterization results. In the singly promoted F1.2WZ catalyst, we suggest that the iron species promotes the n-butane isomerization reaction through a redox effect. The formation of W–O–Fe linkag...
متن کاملn-Butane Isomerization Catalyzed by Sulfated Zirconia Nanocrystals Supported on Silica or γ-Alumina
Supported sulfated zirconia catalysts with zirconia contents of 10, 20 and 50 wt% were prepared by impregnation of SiO2 and γ-Al2O3 supports with H2SO4/Zr(SO4)2 solutions followed by calcination at 923 K. The catalysts were characterized by X-ray diffraction, extended X-ray absorption fine structure measurements, thermal analysis, UV–vis spectroscopy, and electron microscopy. Tetragonal zirconi...
