Abstract

Catalytic hydropyrolysis combines fast pyrolysis with catalytic upgrading by hydrodeoxygenation (HDO) in a single step for the production of fuel oil from biomass in which reactive pyrolysis vapors are upgraded before condensation. Catalyst activity and lifetime is challenged by carbon deposition and by the presence of alkali, nitrogen, sulfur and water. In this contribution, a combined experimental, characterization (in-situ Extended X-Ray Absorption Fine Structure, EXAFS) and theoretical (Density Functional Theory, DFT) study of catalytic HDO of biomass model compounds over MoS2 based catalysts is presented with emphasis on the influence of water and H2S.
