Abstract

Fast pyrolysis of biomass produces a high yield of bio-oilthrough well-established technologies [1]. To utilize this oil as liquid fuel the oxygen content must be reduced from 15-30 wt.% down to <1 wt.%, which increases heating value and stability and decreases acidity [1]. Upgrading bio-oil by catalytic hydrodeoxygenation (HDO) is challenged by severe polymerization and coking upon heating the oil. Alternatively, performing fast pyrolysis in high-pressure hydrogen atmosphere in a fluid bedreactor with a HDO catalyst as bed medium, could immediately stabilize reactive pyrolysis vapors [2]. An additional HDO reactor could ensure removal of oxygen down to <1 wt%. A schematic diagram for such a processis shown in Figure 1. A simplified bench scale setup has been constructed at DTU Chemical Engineering for proof-of-concept for the continuous conversion of solid biomass to low oxygen, fuel-grade bio-oil.
