Fast pyrolysis system for bio‐oil production using conical spouted bed reactor. Copyright: Hoon Chae Park, Yonsei University The spouted‐bed reactor is an alternative to the fluidized‐bed reactor and is used as a fast pyrolysis reactor for biomass and waste. The main advantages of a spouted‐bed reactor are the high heat and mass transfer rates, good particle movement, and low operation cost. The volume of a spouted‐bed reactor is smaller than that of a fluidized‐bed reactor for the same capacity, and no gas distributor plate is required. Furthermore, it could attain very low gas residence times. The spouted‐bed reactor has been successfully used for the fast pyrolysis of both biomass and other residues such as tire, sewage sludge, and plastic. Fast pyrolysis experiments of larch sawdust were conducted in a conical spouted‐bed reactor to study the influences of reaction temperature, inlet gas velocity, feeding rate, and particle size on the product yield and pyrolysis oil quality: DOI: 10.1002/ceat.201900082
