Catalytic transfer hydrogenation of furfural to furfuryl alcohol over calcined MgFe hydrotalcites
(Elsevier B.V., 2019-11-07)Catalytic transfer hydrogenation is an alternative catalytic approach for the reduction of carbonyl groups, instead of the use of dihydrogen gas. In this sense, a series of catalysts has been prepared by thermal treatment ... -
Evaluation of the ZrO2/Al2O3 system as catalysts in the catalytic transfer hydrogenation of furfural to obtain furfuryl alcohol
(Elsevier, 2021)ZrO2, Al2O3 and ZrO2/Al2O3 with different Zr/Al molar ratio, have been synthesized by coprecipitation and subsequent calcination. The resulting catalysts were characterized by X-ray diffraction, transmission electron microscopy, ... -
Mixed Oxides Derived from Hydrotalcites Mg/Al Active in the Catalytic Transfer Hydrogenation of Furfural to Furfuryl Alcohol
(IOAP-MDPI, 2022-12-26)Herein, a family of Mg/Al hydrotalcites was synthesized as catalytic precursors of MgAlOx mixed oxides. Both hydrotalcites and mixed oxides were characterized and the mixed oxides were tested in the reduction of furfural ... -
Recovery of pentoses-containing olive stones for their conversion into furfural in the presence of solid acid catalysts
(2020-06-24)Olive stones were employed as feedstock for furfural production in two stages: 1) autohydrolysis of hemicellulosic fraction to recover their pentoses, mainly xylose, and 2) subsequent dehydration of pentoses into furfural. ... -
Selective production of furan from gas-phase furfural decarbonylation on Ni-MgO catalysts.
(American Chemical Society, 2019-03-13)A series of Ni-MgO catalysts (Ni/Mg molar ratio: 0.1-0.3), prepared by a coprecipitation-calcination-reduction methodology, was characterized and evaluated in the gas-phase hydrogenation of furfural. In all cases, after ... -
Synthesis of Porous Clay Heterostructures Modified with SiO2–ZrO2 Nanoparticles for the Valorization of Furfural in One-Pot Process
(Wiley-VCH GmbH, 2022)The layered structure of two smectites (montmorillonite and saponite) are modified by the insertion of SiO2–ZrO2 nanoparticles, with a Si/Zr molar ratio of 5, to form porous clay heterostructures (PCHs). These PCHs exhibit ... -
Tailoring the selectivity of Cu-based catalysts in the furfural hydrogenation reaction: Influence of the morphology of the silica support
(Elsevier, 2022)Cu nanoparticles were incorporated on different porous silica supports (commercial silica, SBA-15 synthesized both at room temperature and under hydrothermal conditions, and mesocellular foam) by the strong electrostati ... -
The Role of Copper in the Hydrogenation of Furfural and Levulinic Acid
(IOAP-MDPI, 2023-01-26)Currently, there is a great interest in the development of sustainable and green technologies for production of biofuels and chemicals. In this sense, much attention is being paid to lignocellulosic biomass as feedstock, ... -
The role of nitride species in the gas-phase furfural hydrogenation activity of supported nickel catalysts
(Elsevier B.V., 2020-03-11)A series of C-rich nickel nitride nanoparticles supported on silica has been prepared by the urea glass route, with urea as nitrogen and carbon source, and characterized by different physico-chemical techniques. They consist ...
