Deactivation of Cu–Mg–Al mixed oxide catalysts for liquid transportation fuel synthesis from biomass-derived resources
(Elsevier B.V., 2018-08)
A “platform molecule” (2-hexanol) obtained from the primary conversion of sugars was upgraded to liquid transportation fuel precursors under gas phase conditions at 573 K and 101.3 kPa. Reaction was promoted by Cu-Mg-Al ...
Upgrading of biomass-derived 2-hexanol to liquid transportation fuels on Cu-Mg-Al mixed oxides. Effect of Cu content
(Elsevier, 2016-03)
The gas-phase synthesis of high molecular weight compounds of application as liquid transportation fuels from 2-hexanol was studied on Cu-Mg-Al mixed oxides with different copper content (0.3-61.2%) and a Mg/Al =1.5 molar ...
Conversion of Biomass-Derived 2-Hexanol to Liquid Transportation Fuels: Study of the Reaction Mechanism on Cu–Mg–Al Mixed Oxides
(Springer/plenum Publishers, 2015-07)
The reaction mechanism of 2-hexanol conversion to high molecular weight compounds to be used as liquid transportation fuels was studied on MgO, Cu/SiO2 and a bifunctional Cu-Mg-Al mixed oxide with 8 wt. % Cu (catalyst ...
Catalytic hydrogenation of dihydrolevoglucosenone to levoglucosanol with a hydrotalcite/mixed oxide copper catalyst
(2019-01-01)
Levoglucosanol (LGOL) is a critical intermediate for the bio-based production of hexane-1,2,5,6-tetrol, 1,2,6-hexanetriol, and 1,6-hexanediol. Here we report on the aqueous-phase hydrogenation of cellulose-derived ...
Butanol synthesis from ethanol over CuMgAl mixed oxides modified with palladium (II) and indium (III)
(2018-08-01)
Ethanol conversion to butanol was investigated over mixed oxides derived from hydrotalcites modified with copper, palladium or indium. The reaction was carried out in the 403–573 K temperature range using stainless steel ...
Hydrodeoxygenation of furfuryl alcohol over Cu/MgAl and Cu/ZnAl catalysts derived from hydrotalcite-like precursors
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2017-01-01)
The aqueous phase hydrodeoxygenation (HDO) of furfuryl alcohol over Cu/MgAl and Cu/ZnAl catalysts with different Mg/Al and Zn/Al molar ratios, were investigated. Mg-Al and Zn-Al mixed oxides derived from hydrotalcites ...
Ethanol condensation at elevated pressure over copper on AlMgO and AlCaO porous mixed-oxide supports
(2019-01-01)
The coupling of ethanol to produce C4-compounds by Guerbet condensation at 325 °C was studied using porous mixed oxide catalysts of AlMgO and AlCaO prepared by the emulsion mediated method with and without the addition of ...
Liquid transportation fuels from biomass-derived oxygenates: Gas-phase 2-hexanol upgrading on Cu-based mixed oxides
(Elsevier Science, 2015-01)
The gas-phase upgrading of 2-hexanol, a model molecule of the primary conversion of sugars, toward higher molecular weight compounds of application as liquid transportation fuels was investigated on Cu-MI-MII mixed oxides ...
Ethanol dehydrogenative reactions catalyzed by copper supported on porous Al-Mg mixed oxides
(2019-01-01)
Mixed aluminum and magnesium oxides (AlMgO) prepared by means of an emulsion-mediated sol-gel method was impregnated with copper nitrate solution and used in the ethanol dehydrogenative reactions to produce acetaldehyde ...
