Abstract

Abstract: The technology of biomass fast pyrolysis in the spout-fluidized bed with a draft tube is summarized. The theoretical principles and process characteristics of the technology are reviewed respectively on reaction mechanism, hydrokinetics, heat and mass transfer, solid and vapour residence time, flow regime map, pyrolysis products collection and disposal. Comparison of the spout-fluidized bed with a draft tube and other fluidized beds are conducted. Finally, development directions of the technology of biomass fast pyrolysis in the spout-fluidized bed with a draft tube are put forward.

Key words: the spout-fluidized bed, biomass, fast pyrolysis
