Experimental study of Biomass Fast Pyrolysis for Bio-oil
Experiments of the rotating cone reactor and in fluidized bed reactor for sawdust fast pyrolysis are conducted. For the rotating cone reactor fast pyrolysis, the mass and energy balance analyses are carried out. The bio-oil mass and energy conversion rates are 53.37wt％ and 42％, respectively, when the reactor temperature and sawdust throughput were 600℃ and 26.42 kg/h. The effects of process conditions, like fluidized bed reactor temperature, feed size and vapor residence time on the product yields are studied in fluidized bed reactor with sawdust of 0-0.90 mm. The yield of bio-oil is maximum (58.23wt％ of biomass feed) for the particle size of 0.45-0.60 mm with a char yield of 8.23wt％. Vapor residence times are ranged from 0.80 to 1.50 s at temperature of 500℃ with a particle size less than 0.20 mm. A maximum bio-oil yield of 62.60wt％ is achieved at 500℃ when the vapor residence time is held constant at 0.80 s. However, at the longer residence time (1.50 s), bio-oil yield is slightly lower. Bio-oil is a miscible mixture of polar organics and water. The results show the potential of sawdust fast pyrolysis for bio-oil production.
