Production of Bio Oil by Using Larch Sawdust in a Bubbling Fluidized Bed Reactor
Fast pyrolysis experiments of larch sawdust by using a bubbling fluidized bed (0.076 m I.D. x 0.8 m high) have been investigated to determine, particularly, the effect of temperature, U-o/U-mf ratio, length/diameter ratio of bed (L/D), particle size of the bed material, and O-2 concentration on the bio oil yield and compositions. The operation conditions were as follows: temperature, 350550 degrees C; L/D, 1.03.0; U-o/U-mf ratio, 2.06.0; particle size, 60128 m; and O-2 concentration, 015 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 degrees C; L/D ratio, 2.0; and O-2 concentration, 0%.
