Mono- and bimetallic UiO-66 nanocatalysts were synthesized using the solvothermal synthesis method evaluated in aldol condensation reaction of benzaldehyde acetone a batch reactor. N2 physisorption, thermogravimetric analysis, temperature-programmed desorption ammonia, X-ray diffraction, field-emission scanning electron microscopy–energy-dispersive X-ray, photoelectron spectroscopy, potentiometric titration, Fourier transform infrared used to characterize nanocatalysts. The higher activity...
Zr( iv ), Ce( and Hf( the linkers BDC PDC has been fully studied for CO 2 adsorption capability.
Experimental data analysis and Monte Carlo simulations showed that sewage sludge can be successfully stabilized using HTL; overall energy recovery increased up to 2.2-fold relative an AD-only treatment.
In this work the adsorption of 4,6-dimethyldibenzothiophene (4,6-DMDBT) on different supports (SiO 2 , Al O 3 zeolite 4A, 13X, natural zeolite, and activated carbon), incorporating its surface first series transition metal oxides at content, was studied.The results indicate that carbon presents a higher capacity than other studied, which it is assumed to large number functional groups present surface.The incorporation support, induces in some cases increase capacities 4,6-DMDBT these...
The benzaldehyde acetalization catalyzed by UiO-66 and UiO-66F, was carried out in a batch-type reactor at room temperature atmospheric pressure, the full kinetic study performed using Langmuir–Hinshelwood Eley–Rideal models.
The removal of 4-Nitrophenol (4-NP) from aqueous media by adsorption is studied in a batch system using different porous materials: activated carbon, zirconia, alumina, sepiolite, natural zeolite and 13X zeolite.Depending on their capacities, the best adsorbent was chosen to be impregnated with levels nickel (Ni) order study π-complexation continuous systems.The samples Ni(x)/support (x= 2, 4, 6%) were prepared wet impregnation characterised same method as all materials, N 2...
In this work we have carried out the adsorption of pyridine using three different supports (activated carbon, SiO 2 and γ-Al O 3 ).After choosing best support, due to its higher capacity, impregnated support with nickel at concentrations (2, 4 6% w/w) by wet impregnation study π-complexation.All samples (supports adsorbents) were characterized N adsorption-desorption BET method electrophoretic migration.The experimental results, for supports, show that capacity is better 3, isoelectric...
The simultaneous adsorption of quinoline and 4,6-dimethyldibenzothiophene over adsorbents, based on alumina modified with boron nickel under ambient temperature pressure, was studied. adsorbents were characterized by BET specific surface area, a potentiometric method for the determination acid strength, electrophoretic migration, X-ray diffraction. results showed that adsorbent containing had better capacity than boron, which attributed to its greater acidity ability generate π-complexation...
The influence of fluorine concentration on the synergism between Co/γ-Al 2 O 3 and Mo/γ-Al stacked beds separated by 3-mm γ-Al F x (x = 0 -2.5%), in hydrodesulphurization refractory molecules contained gasoil, under operating conditions similar to those industry, was studied.The results shown, that increases with content, reaching a maximum at 0.8% fluorine, which it is related changes zero point charge (ZPC) acid strength, due incorporation fluorine.The conversion most molecule reported...
A novel set of four functionalized hydrophobic UiO-66-NHR series were synthesized through postsynthetic procedures, utilizing various benzoyl chlorides and UiO-66-NH
This study analyses the hydrodenitrogenation (HDN) of pyridine using a stacked bed catalyst system, composed first hydrogenating Re/γ-Al 2 O 3 or W/γ-Al , over second Ni-Re/γ-Al (HDN bed).Using potentiometric methods, it can be seen that shows higher acidic strength than .The results show activity levels are obtained working with systems compared to separate catalysts.These suggest incorporation beds would favour formation hydrogenated intermediary products, facilitating removal N-containing...
The effect of supports and the addition CS2 in feed were studied on hydrodenitrogenation Quinoline a continuous flow reactor over ReS2/support catalysts at 300, 325 350 °C 3MPa H2. ReS2 supported TiO2 displayed highest activity followed by ZrO2, γ-Al2O3 SiO2 supports. trend was correlated with Re dispersion support. increased until 2.5 v/v % content. At higher content decreased due to competitive adsorption between active sites.
