In this study, a bubbling fluidized bed pyrolyzer (0.076 m I.D. and 0.8 m high) was employed to investigate the fast pyrolysis characteristics of larch sawdust which is abundant in Korea. The effects of operation conditions, such as bed temperature (350-550 ℃), fluidization velocity ratio (Uo/Umf : 2.0-6.0) and feeding rate (2.2-7.0 g/min) on product yields and their chemical components were studied. The number of chemical compounds in the bio-oil decreased with the increasing bed temperature because of secondary pyrolysis. The effects of the Uo/Umf ratio and feeding rate on bio-oil compositions were relatively lower than those of the bed temperature.
