Biobased Vanillin Production by Oxidative Depolymerization of Kraft Lignin on a Nitrogen- and Phosphorus-Functionalized Activated Carbon Catalyst
(ACS, 2024-04-04)The sustainable production of vanillin from the oxidative depolymerization of lignin was evaluated. Vanillin was produced from Kraft lignin using heterogeneous catalysts based on activated carbons prepared by chemical ... -
Biomass-derived activated carbon catalysts for the direct dimethyl ether synthesis from syngas
(Elsevier, 2024-02-27)The direct DME synthesis from syngas was studied by using activated carbon-based bifunctional catalytic beds. Two kinds of activated carbons, prepared by physical (by CO2 partial gasification) and chemical (with phosphoric ... -
Carbon-based materials as Catalyst Supports for Fischer–Tropsch Synthesis: a review
(Frontiers, 2021-02-04)The use of carbon-based materials as catalyst supports for Fischer–Tropsch synthesis (FTS) is thoroughly reviewed. The main factors to consider when using a carbonaceous catalyst support for FTS are first discussed. Then, ... -
Deactivation of a Biomass-Derived Zirconium-Doped Phosphorus-Containing Carbon Catalyst in the Production of Dimethyl Ether from Methanol Dehydration
(ACS, 2021-08-31)Dehydration of methanol to produce dimethyl ether (DME) was studied at relatively high temperatures (400–600 °C) on biomass-derived phosphorus-containing carbon impregnated with a zirconium salt. Highly thermally stable ... -
NiGa Unsupported Catalyst for CO2 Hydrogenation at Atmospheric Pressure. Tentative Reaction Pathways
(American Chemical Society, 2021-12-06)The hydrogenation of CO2 is presented as a catalytic strategy for CO2 utilization and an approach to the development of sustainable processes to obtain products with high added value, such as CO, CH4, and CH3OH. An unsupported ... -
Operando Reactor-Cell with Simultaneous Transmission FTIR and Raman Characterization (IRRaman) for the Study of Gas-Phase Reactions with Solid Catalysts.
(American Chemical Society, 2020-03-10)Raman and transmission FTIR spectroscopic techniques have been coupled in a new homemade reactor-cell designed in a joint CSIC–LCS collaboration. The setup is easily adapted to any FTIR and fiber-coupled Raman spectrometers ...
