Surface‐Dependent Activation of Model α‐Al2O3‐Supported P‐Doped Hydrotreating Catalysts Prepared by Spin Coating

Ricardo Garcia de Castro, Jérémy Bertrand, Baptiste Rigaud, Elodie Devers, Mathieu Digne, Anne‐félicie Lamic-Humblot, Gerhard Pirngruber, Xavier Carrier

Requirements for improved catalytic formulations is continuously driving research in hydrotreating (HDT) catalysis for biomass upgrading and heteroatom removal for cleaner fuels. The present work proposes a surface-science approach for the understanding of the genesis of the active (sulfide) phase…

Aqueous-Phase Preparation of Model HDS Catalysts on Planar Alumina Substrates: Support Effect on Mo Adsorption and Sulfidation

Cédric Bara, Lucie Plais, Kim Larmier, Elodie Devers, Mathieu Digne, Anne-Félicie Lamic-Humblot, Gerhard D. Pirngruber, Xavier Carrier

The role of the oxide support on the structure of the MoS2 active phase (size, morphology, orientation, sulfidation ratio, etc.) remains an open question in hydrotreating catalysis and biomass processing with important industrial implications for the design of improved catalytic formulations. The…

Characterization of mesoporous alumina prepared by surface alumination of SBA-15

Manuel Baca, Emmanuel de La Rochefoucauld, Emmanuelle Ambroise, Jean-Marc Krafft, Redouane Hajjar, Pascal P. Man, Xavier Carrier, Juliette Blanchard

Mesoporous aluminas of controlled pore sizes were synthesized by multiple grafting of Al isopropoxide in organic solvents on mesoporous silica SBA-15. These materials were characterized by N2 physisorption, TEM, XRD, 27Al NMR and their surface chemical properties were probed by DRIFT, cumene…
