Abstract
Bio-oil/char slurry from wood biomass is an attractive and novel fuel with advantages in energy density, storage and transportation. In this paper, fundamental characteristics of fluidized bed system for fast pyrolysis is presented as improved pyrolysis reactor of our earlier system. This system shows good performance for short residence time close to a few seconds. Influences of the location of biomass supply in a fluidized bed and the resident time on yields quantity and quality are clarified. The property of the yields is shown that the high quality (high-heating value) of bio-oil is obtained under the short residence time.
