Fast pyrolysis experiments of larch sawdust by using a bubbling fluidized bed (0.076 m I.D. × 0.8 m high) have been investigated to determine, particularly, the effect of temperature, Uo/Umf ratio, length/diameter ratio of bed (L/D), particle size of the bed material, and O2 concentration on the bio oil yield and compositions. The operation conditions were as follows: temperature, 350-550°C; L/D, 1.0-3.0; U o/Umf ratio, 2.0-6.0; particle size, 60-128 μm; and O2 concentration, 0-15 vol%. As bio oil yield decreased with operation conditions, the gas yield increased and the number of chemical compounds in bio oil decreased. The maximum oil yield of 58 wt% was obtained at: temperature, 400°C; L/D ratio, 2.0; and O2 concentration, 0%.
