Box 644, E48080 Bilbao, Spain GR APHICAL A BSTRACT ARTICLE I NFO ABSTRACT Keywords: The eﬀect of reforming conditions (temperature, space time and steam/biomass ratio (S/B)) has been studied in Biomass the continuous biomass pyrolysis and in-line catalytic steam reforming process in order to establish suitable Pyrolysis conditions for attenuating the deactivation of a commercial Ni catalyst by coke deposition. The experiments have Reforming been performed in a conical spouted bed and a ﬂuidized bed reactor for the pyrolysis and reforming steps, Hydrogen respectively. Biomass fast pyrolysis was performed at 500 °C and the reforming operating conditions studied are Deactivation −1 as follows: 550–700 °C; space time, 10–30 g min g , and; S/B ratio, 2–5. The coke deposited on the cat volatiles Bio-oil catalyst has been analyzed by temperature programmed oxidation (TPO), and two types of coke
