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 Catalizadores Biomasa Sepiolita Hidrogenación 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 behavior, reaching a maximum furfural conversion above 80% after 5 h of reaction at 210 ºC. In all cases, the main product is furfuryl alcohol, obtaining 2-methylfuran in lower proportions. The incorporation of these metal oxide species ameliorates the dispersion of metallic Cu nanoparticles, increasing the number of available Cu(0)-sites, which enhances the catalytic performance. The presence of acid sites favors the hydrogenolysis of furfuryl alcohol towards 2-methylfuran, although it also causes an increase of carbon species on its surface, which is associated with the catalytic deactivation of the catalyst along the time-on-stream. 2022-03-03T11:48:18Z 2022-03-03T11:48:18Z 2019 2019-03-31 journal article https://hdl.handle.net/10630/23798 10.3390/catal9040315 eng http://creativecommons.org/licenses/by-nc-nd/4.0/ open access Attribution-NonCommercial-NoDerivatives 4.0 Internacional MDPI
