A new type of mobile fast pyrolysis equipment with annular tube fluidized bed reactor was designed and built throughput capacity of over 50kg/h. The structure of main components such as the annular tube fluidized bed reactor, fluidized pneumatic conveying feeder, jetspray combined condenser and so on was described in detail, and the experiments were carried out to test the performance of each part of the mobile fast pyrolysis equipment. The results showed that the feeding rate was greatly influenced by the injection gas velocity, and was less affected by the fluidized gas velocity. When the fluidized gas velocity was 0.02m/s, as the injection gas velocity was increased, the feeding rate was increased, whereas the injection gas velocity exceeded 8m/s, the trend was slowed and the feeding rate fluctuation range became larger. The annular tube fluidized bed reactor was heated by means of burning liquefied petroleum gas and noncondensable gas, and the internal temperature field of the fluidized bed reactor was stable, which met the needs of biomass thermal cracking. Jetspray combined condenser was suitable for the cooling of the pyrolysis volatiles. In order to increase the yield of biooil, a larger spray flow rate and jet flow rate were required at a given temperature. At reaction temperature of 500℃, the highest biooil yield of larch sawdust could reach 68.6%. The research can provide a referenced basis for the mobile biomass pyrolysis liquefaction demonstration plant.
