Biodiesel produced through catalytic transesterification of triglycerides from edible and non-edible oils alcohol is considered an alternative to traditional petro-diesel. The interest in the use alkaline earth metal oxides as heterogeneous basic catalysts has increased due their availability, non-toxicity, capacity be reused, low cost, high concentration surface sites that provide activity. This work a compilation strategies understand effect source, synthesis, thermal treatment MgO, CaO,...
Abstract In this study, we investigated the performance of graphene oxide (GO)-based catalysts, including commercially available GO, GO synthesized via All Kemie Sus method, and GO/TiO 2 composites, for CO reduction under both UV visible light irradiation. The catalysts were systematically characterized using XRD, SEM, FTIR, EDS, UV, XPS techniques to elucidate their structural chemical properties. Our findings reveal remarkable versatility these materials, demonstrating ability produce a...
Ni/Al2O3 and NiFe/Al2O3 catalysts were synthesized by incipient wetness impregnation tested for oxidative dehydrogenation (ODH) of ethane to ethylene. The effect Ni loading Fe as a promoter bimetallic characterized X-ray diffraction (XRD), Raman spectroscopy, ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS), scanning electron microscopy (SEM), temperature-programmed reduction (H2-TPR). catalyst with 10 wt% 6.6 (NiFe32) displayed the highest ODH activity. XRD results showed...
Catalytic propane dehydrogenation is an attractive method to produce propylene while avoiding the issues of its traditional synthesis via naphtha steam cracking naphtha. In this contribution, a series Pt-Sn/SBA-16 catalysts were synthesized and evaluated for purpose. Bimetallic Pt-Sn more active than containing only Pt. The catalyst with best performance was assessed at different reaction times 0, 60, 180, 300 min. evolution coke deposits also studied. Thermogravimetric analysis demonstrated...
The effects of the synthesis method, dopant nature, and porosity on dibenzothiophene hydrodesulfurization performance hierarchically porous NiMoS(Si,Zr)/Al2O3 catalysts were studied. Si Zr incorporation was carried out using grafting (G) sol–gel (SG) methods. characterized scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), N2 physisorption, Hg intrusion porosimetry (MIP), diffraction, hydrogen temperature-programmed reduction (H2-TPR), pyridine-adsorbed Fourier...
La integration (at various nominal contents) in SBA-15 prepared under acidic medium was intended from corresponding direct nitrate addition during mesoporous silica formation. Materials were impregnated with Pt (1.5 w%) and studied through several textural (N2 physisorption), structural (XRD, TG-DTG) surface (FTIR, STEM-HAADF, SEM-EDS, NH3 CO2 TPD) instrumental techniques. Pt-impregnated solids tested phenol hydrodeoxygenation (HDO, T=250 °C, 3.2 MPa, batch reactor, n-decane as solvent)....
Abstract BACKGROUND The composite materials ZrO 2 /Zn 5 (OH) 6 (CO 3 ) were prepared in only one step by chemical co‐precipitation and thermal hydrolysis of urea. was added at 5, 8 10 mol%. samples dried 80 °C characterized adsorption–desorption N isotherms, X‐ray diffraction (XRD) scanning electron microscopy (SEM) techniques, diffuse reflectance (DRS), UV–visible, Fourier‐transform infrared (FTIR) photoelectron (XPS) spectroscopies. assessed the photodegradation phenol polychlorinated...
Abstract In this paper, the phenol mineralization by Ce 3+ ‐doped CeO 2 photocatalysis at room temperature, is shown for first time. The photocatalytic behavior of was improved through incorporation into its crystalline lattice. materials were prepared precipitation method low temperatures varying 4+ :Ce molar ratio precursors during synthesis process. It worth noting that, synthesized photocatalysts did not carry out a thermal treatment after their preparation. results obtained from Raman...
In the present work, phenol was used as a model molecule to photocatalytic evaluation of TiO2 impregnated with iron sulphide and chlorine on visible-light reactor. The iron–chlorine catalyst prepared by incipient impregnation metal precursors, Fe (NO3)3 NaCl previously calcined TiO2. sulphurized H2S at 300 °C for 1 h. catalysts were different concentrations using HYDRA chemical equilibrium diagrams obtain fractions FeCl+. oxide characterized diffuse reflectance (DRS UV–Vis) temperature...
This paper reports the effects of changes in supported active phase concentration over titania containing mixed oxides catalysts for hydrodeoxygenation (HDO). Mo and CoMo on sol–gel Al2O3–TiO2 (Al/Ti = 2) were synthetized tested HDO phenol a batch reactor at 5.5 MPa, 593 K, 100 ppm S. Characterization results showed that increase loading led to an amount oxide species with octahedral coordination (MoOh), which produced more sites augmented catalytic activity. The study change Co allowed...
Abstract This paper presents the synthesis of ZnS through solvothermal method using hydrozincite (Zn 5 (CO 3 ) 2 (OH) 6 as a precursor. Zinc sulfide (ZnS) was synthesized at four different temperatures: 80 °C, 100 140 and 180 °C. All photocatalysts that were underwent characterization by X‐ray diffraction, scanning electron microscopy, infrared spectroscopy, thermogravimetric analysis, N adsorption‐desorption isotherms, diffuse reflectance photoelectron analysis.
