11 Catalytic hydropyrolysis of beech wood was conducted in a fluid bed reactor at 450°C and a total pressure 12 of 26 bar. The differences in hydrodeoxygenation activity, selectivity and the resulting product composition 13 between sulfided Mo/MgAl 2 O 4 , CoMo/MgAl 2 O 4 or NiMo/MgAl 2 O 4 catalysts have been investigated. The 14 acidity and molybdate species in the oxide catalyst precursors were characterized with ammonia 15 temperature programmed desorption (NH 3-TPD) and Raman spectroscopy. The spent sulfided catalysts 16 were also extensively characterized by scanning electron microscopy (SEM) and by scanning transmission 17 electron microscopy (STEM) coupled with energy dispersive X-ray spectroscopy (EDS). The catalytic 18 hydropyrolysis of beech wood produced four kinds of products: Liquid organic and aqueous phases, solid 19 char and gases. The solid char and aqueous phase yields were not affected by the type of catalyst. The sum 20 of condensed organics and C 4+ gas yield varied between 24.3 and 26.4 wt.% on dry, ash free basis (daf) and 21 was highest for the Mo catalyst and lowest for the NiMo catalyst. The NiMo catalyst had the highest 22 hydrogenation, cracking, and de-carbonylation activity. The oxygen content in the condensed organic phase 23 was between 9.0 and 12 wt.% on dry basis (db) and was lowest for the CoMo catalyst and highest for the
