Effect of the treatment with H3PO4 on the catalytic activity of Nb2O5 supported on Zr-doped mesoporous silica catalyst. Case study: glycerol dehydration.
García-Sancho, Cristina; Cecilia-Buenestado, Juan Antonio; Mérida-Robles, Josefa María; Santamaría-González, José; Moreno-Tost, Ramón; Infantes-Molina, Antonia; Maireles-Torres, Pedro Jesús[et al.] (Elsevier B.V., 2017-09-06)We have previously demonstrated the influence of the niobium species over the glycerol dehydration reaction and how the catalyst regeneration by thermal treatment modified the catalytic performance due to the transformation ... -
Evaluation of the ZrO2/Al2O3 system as catalysts in the catalytic transfer hydrogenation of furfural to obtain furfuryl alcohol
Jiménez-Gómez, C.P.; Viar-Antuñano, N.; Cecilia-Buenestado, Juan Antonio; Moreno-Tost, Ramón; Mérida-Robles, Josefa María; Requies, J.; Maireles-Torres, Pedro Jesús[et al.] (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, ... -
Influence of the Incorporation of Basic or Amphoteric Oxides on the Performance of Cu-Based Catalysts Supported on Sepiolite in Furfural Hydrogenation
Guerrero-Torres, Antonio; Jiménez-Gómez, Carmen Pilar; Cecilia-Buenestado, Juan Antonio; García-Sancho, Cristina; Quirante-Sánchez, José Joaquín; Mérida-Robles, Josefa María; Maireles-Torres, Pedro Jesús[et al.] (MDPI, 2019-03-31)Cu-based catalysts supported on sepiolite have been tested in vapor-phase hydrogenation of furfural. The incorporation of basic or amphoteric metal oxides (magnesium oxide, zinc oxide, or cerium oxide) improves the catalytic ... -
Recent Advances in Mechanochemical Pretreatment of Lignocellulosic Biomass
Pérez Merchán, Antonio Manuel; Rodríguez Carballo, Gabriela; Torres-Olea, Benjamín; García-Sancho, Cristina; Maireles-Torres, Pedro Jesús; Mérida-Robles, Josefa María; Moreno-Tost, Ramón[et al.] (IOAP-MPDI, 2022-08-17)Biorefineries are industrial facilities where biomass is converted into chemicals, fuels and energy. The use of lignocellulose as raw material implies the development of pretreatments to reduce its recalcitrant character ... -
Tailoring basic and acidic properties of MgAl hydrotalcite by fluoride anions: Effect on glycerol oligomerisation
Maderuelo Solera, Rocío; Ledesma-Muñoz, A.L.; García-Sancho, Cristina; Cecilia-Buenestado, Juan Antonio; Infantes-Molina, Antonia; Mérida-Robles, Josefa María; Maireles-Torres, Pedro Jesús; Moreno-Tost, Ramón[et al.] (Elsevier, 2023)In this work, two families of catalysts based on mixed metal oxides derived from MgAl hydrotalcites were synthesized with a Mg/Al molar ratio of 3. On the one hand, in the first family, the fluoride anion was incorporated ... -
The Role of Copper in the Hydrogenation of Furfural and Levulinic Acid
García-Sancho, Cristina; Mérida-Robles, Josefa María; Cecilia-Buenestado, Juan Antonio; Moreno-Tost, Ramón; Maireles-Torres, Pedro Jesús (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, ...
