Studies on dispersion and reactivity of vanadium oxides deposited on lamellar ferrierite zeolites for condensation of glycerol into bulky products
(2018-10-01)
The acetalization of acetone with glycerol was investigated using vanadium-impregnated catalysts. The siliceous supports FER, a purely microporous material, and ITQ-6, a micro/mesoporous material, were obtained from a ...
High-Active Metallic-Activated Carbon Catalysts for Selective Hydrogenation
(Hindawi Limited, 2018-07)
A series of low-loaded metallic-activated carbon catalysts were evaluated during the selective hydrogenation of a medium-chain alkyne under mild conditions. The catalysts and support were characterized by ICP, hydrogen ...
Catalisadores Ni-Fe/MgAl2O4 na reforma a vapor do etanol: influência da razão molar Ni/Fe nas propriedades catalíticas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2017-03-02)
The effect of iron incorporation on the catalytic properties of Ni / MgAl2O4 for the Ethanol Steam Reforming (ESR) was studied. Samples of different Fe/Ni molar ratios were prepared by wet impregnation of MgAl2O4, synthesized ...
Synthesis, characterization and catalytic activity of modified-clays impregnated with Ni for methane reforming

Acidic V-MCM-41 catalysts for the liquid-phase ketalization of glycerol with acetone
(2019-01-01)
SiMCM-41 and V-MCM-41 were hydrothermally synthesized with different quantities of vanadium, characterized by small angle X-ray scattering, nitrogen physisorption, and the insertion of vanadium was assessed by temperatur ...
Modelamiento del proceso de adsorcion y desorcion de metanol en un lecho de carbón activado para la aplicación en sistemas de refrigeración solar por adsorción intermitente
(2006)
Resumen: Los sistemas de refrigeración por adsorción permiten aprovechar fuentes térmicas no convencionales como la energía solar y desechos de calor residual generados por el proceso industrial. En estos sistemas, no se ...
Isopropanol adsorption–oxidation over V2O5—A mass spectrometry study
(Elsevier Science, 2006-03-16)
The isopropanol adsorption–oxidation over V2O5 (transient study) was monitored by mass spectrometry (MS) of desorbed molecules produced over the catalyst by reactive interaction at 40, 100 and 150 °C. Then temperature ...
Methanol adsorption-oxidation over V2O5 - A mass spectrometry study
(Elsevier Science, 2004-06)
The methanol adsorption-oxidation over V2O5 (transient study) was monitored by mass spectrometry (MS) of desorbed molecules produced over the catalyst by reactive interaction at 40, 100 and 150°C. Then, temperature programmed ...
Catalytic oxidation of 2-(methylthio)-benzothiazole on alkaline earth titanates, ATiO3 (A = Ca, Sr, Ba)
(Elsevier Science, 2017-05)
The effect of the nature of the A-cation in alkaline earth titanates, ATiO3 (A = Ca, Sr, Ba), and the calcination temperature (600 °C, 700 °C) on the catalytic performance for the oxidation of 2-(methylthio)-benzothiazole ...
