Catalytic hydropyrolysis using sulfided Mo, CoMo and NiMo catalysts in a fluid bed reactor

Recent research has shown that catalytic hydropyrolysis of biomass is an efficient process for the production of renewable liquid fuels [1,2]. In this process fast pyrolysis and hydrodeoxygenation (HDO) is combined, ensuring that the reactive oxygenates formed during the pyrolysis, which may participate in polymerization reactions [3], are hydrogenated immediately, thus leading to a stable product with a low oxygen content compared to pyrolysis oil [4].

However, despite being a very promising process, there is very limited information in the open literature regarding the effect of the catalyst in the fluid bed reactor. Therefore, in this work we have tested the effect of using a sulfided CoMo, NiMo, and Mo catalyst in catalytic hydropyrolysis.
