Aluminium-doped catalysts for the high temperature shift reaction
(2002)
The replacement of chromium by aluminium in high temperature shift catalysts was investigated. It was found that aluminium-doped hematite is a convenient candidate as an environmental friendly catalyst.
Influence of Different Types and Concentrations of Chemical Catalysts on Dental Bleaching Efficiency
(2015-11-01)
The objective of this study was to evaluate the effects of different types and concentrations of chemical catalysts on the efficiency of 35% hydrogen peroxide gel on dental bleaching. Enamel-dentin disks were obtained from ...
Hydrogenation of diacetyl over composite-supported egg-shell noble metal catalysts
(Springer, 2017-09)
Two composite supports with a mixed inorganic–organic structure were synthesized: BTAl and UTAl. Hydrophilic–hydrophobic dual properties of the supports were suitable for preparing egg-shell-supported metal catalysts for ...
Ru-Sn-B/TiO 2 catalysts for methyl oleate selective hydrogenation. Influence of the preparation method and the chlorine content
(John Wiley & Sons Ltd, 2019-03)
Background: Fatty alcohols are produced commercially by selective hydrogenation of fattyacid esters using copper and chromium catalysts. To reduce drastic reaction conditions, Ru-Sn catalysts reduced with NaBH4 have been ...
Deactivation and regeneration of Cu/SiO2 catalyst in the hydrogenation of maleic anhydride. Kinetic modeling
(Elsevier Science, 2009-10)
In this work, the deactivation of a Cu(10%)/SiO2 catalyst in the gas-phase hydrogenation of maleic anhydride (MA) was studied. The reaction was performed between 170 and 220 °C, at atmospheric pressure and using two contact ...
Morphological and structural features of Co/TiO2 catalysts prepared by different methods and their performance in the liquid phase hydrogenation of α, β unsaturated aldehydes
(Sociedad Chilena de Química, 2006-03)
The effect of the preparation method of Co/TiO2 catalysts on the performance in the
liquid phase hydrogenation of cinnamaldehyde and crotonaldehyde has been studied. The Co/TiO2 catalysts were prepared by impregnation on ...
Hydrogen Production by Formic Acid Decomposition over Ca Promoted Ni/SiO2 Catalysts: Effect of the Calcium Content
(MDPI, 2019-10)
Formic acid, a major product of biomass processing, is regarded as a potential liquid carrier for hydrogen storage and delivery. The catalytic dehydrogenation of FA to generate hydrogen using heterogeneous catalysts is of ...
Advances in ethanol reforming for the production of hydrogen
(Química Nova, 2014)
Catalytic steam reforming of ethanol (SRE) is a promising route for the production of renewable hydrogen (H2). This article reviews the influence of doping supported-catalysts used in SRE on the conversion of ethanol, ...
Impact of bioethanol impurities on steam reforming for hydrogen production: A review
(International Journal of Hydrogen Energy, 2020-04-17)
Hydrogen fuel cells (H2–FCs) are promising devices for pollution-free and efficient power production. Renewable H2 from biomass is often produced through catalytic ethanol steam reforming (ESR), which requires a steam/ethanol ...
Design of catalyst systems for the one-pot synthesis of menthols from citral
(Academic Press Inc Elsevier Science, 2007-04)
Stable, active, and highly selective bifunctional Ni/Al-MCM-41 catalysts were developed for the one-pot synthesis of menthols from citral. The liquid-phase hydrogenation of citral to citronellal was studied on silica-supported ...
