Abstract Oxygenated compounds methane derivates like formaldehyde and methanol have become important primary chemicals in the manufacturing of various consumer products chemical intermediates used petrochemical sector. This study investigates catalytic conversion over bimetallic particles supported on mordenite alumina. Various catalyst compositions, including Pt‐Ru, Pd‐Ru, Cu‐Ru, were synthesized characterized using techniques such as X‐ray diffraction, nitrogen physisorption, scanning...
The present study optimizes Cu-supported catalysts on hydrotalcite for the synthesis of n-butanol whose interest is in its use as biofuel, due to superior performance comparison with other short-chain alcohols. catalytic was improved by adding Nb formulation. In this way, several Cu-Nb supported hydrotalcites (Mg/Al) different loadings were synthesized incipient wetness impregnation and characterized H2−temperature-programmed reduction, X-ray diffraction, N2 physisorption, CO2−...
Abstract Titanate nanotubes (TiNT) were synthesized by hydrothermal method and used as support of rhodium nanoparticles. Results X‐Ray diffraction (XRD) Raman spectroscopy TiNT revealed its structure Na 2 Ti 3 O 7 , while the results Scanning Electron Microscopy (SEM), Transmission (TEM) physisorption N confirmed multilayer nanotubular morphology with external diameter ∼12 nm, length > 100 nm a BET surface area 195 m g −1 . The TEM analysis supported sample (Rh/TiNT) showed evidence small...
The carbonylation of dimethyl ether to give methyl acetate in the presence a TiO<sub>2</sub>-supported Rh catalyst was investigated by<italic>in situ</italic>infrared spectroscopy. Data indicate intermediate species that are analogous those observed during methanol carbonylation.
This paper investigates for the first time feasibility of lithium recovery using ion-sieves from a Mexican geothermal brine well Cerro Prieto power plant. The materials were prepared following microwave-assisted hydrothermal route to favor their sustainability. Also, effect three manganese-based compounds as precursors was evaluated in which vacancies generated by acid treatment, varying concentration and contact time. structural characterizations showed that manganese sulfate an efficient...
This paper deals with the synthesis and characterization of zeolite type A (ZA) using an agro-industrial residue such as barley husk ecological nonexpensive silica (SiO 2 ) precursor.The amorphous phase was achieved by pyrolysis then used to form a synthetic gel in typical hydrothermal procedure where carbonaceous removed calcination afterwards.The prepared materials X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy techniques carried out.ZA evaluated removal...
Abstract Ru nanoparticles supported on titanate nanotubes (Ru/TiNT) were catalytically active in the ethylene hydroformylation using CO 2 as reactant (at atmospheric pressure and moderate temperatures) to give propanal ethane. The rate of formation at 100 °C with a molar feed ratio 1 : 8 (CO C H 4 Ar) was 0.128 mol −1 h . Raman spectra X‐ray diffraction data characterizing catalyst confirmed presence crystalline structure Na Ti 3 O 7 for TiNT, whereas transmission electron microscopy (TEM)...
Direct conversion of CO 2 and H to methyl acetate via the methanol hydrocarboxylation catalyzed by titanate nanotube-supported Rh Ru catalysts: infrared spectroscopy evidence surface species.
Thermophysical properties are important to design the fuel system components and evaluate new alternative fuels in diesel engine tests. Also, experimental allow us understand type of interactions present studied mixtures. Densities, viscosities, refractive indices biodiesel + ethyl levulinate, acetoacetate, pyruvate with MgO mixtures have been measured from 288.15 338.15 K at 0.1 MPa over whole composition range a constant concentration 5 × 10–6 mass fraction for MgO.
