Glucose–Carbon Hybrids as Pt Catalyst Supports for the Continuous Furfural Hydroconversion in Gas Phase Morales Torres, Sergio Pastrana Martínez, Luisa María Pérez García, Juan A. Maldonado Hodar, Francisco José Active carbon Carbon nanotubes Deactivation Decarbonylation Furan Furfural Furfuryl alcohol Glucose Hydroconversion Pt-catalysts Glucose–carbon hybrids were synthetized with different carbon materials, namely carbon nanotubes, reduced graphene oxide, carbon black and activated carbon by a hydrothermal treatment. These carbon hybrids were used as Pt-supports (1 wt.%) for the furfural (FUR) hydroconversion in the gas phase at mild operating conditions (i.e., P = 1 atm and T = 200 ◦C). The physicochemical properties (porosity, surface chemistry, Pt-dispersion, etc.) were analyzed by different techniques. Glucose– carbon hybrids presented apparent surface areas between 470–500 m2 g −1 , a neutral character and a good distribution of small Pt-nanoparticles, some large ones with octahedral geometry being also formed. Catalytic results showed two main reaction pathways: (i) FUR hydrogenation to furfuryl alcohol (FOL), and (ii) decarbonylation to furane (FU). The products distribution depended on the reaction temperature, FOL or FU being mainly produced at low (120–140 ◦C) or high temperatures (170–200 ◦C), respectively. At intermediate temperatures, tetrahydrofurfuryl alcohol was formed by secondary FOL hydrogenation. FUR hydroconversion is a structure-sensitive reaction, roundedshape Pt-nanoparticles producing FU, while large octahedral Pt-particles favor the formation of FOL. Pt-catalysts supported on glucose–carbon hybrids presented a better catalytic performance at low temperature than the catalyst prepared on reference material, no catalyst deactivation being identified after several hours on stream. 2021-03-02T11:29:54Z 2021-03-02T11:29:54Z 2021 info:eu-repo/semantics/article Morales-Torres, S.; Pastrana-Martínez, L.M.; Pérez-García, J.A.; Maldonado-Hódar, F.J.
