The fluidizated bed reactor developed by the researchers of the Unicamp in the installations of the Sugar Cane Technology Center (CTC), in Piracicaba-SP, is the first reactor of biomass fast pyrolysis in Brazil to produce bio-oil. In this work the problems of operation with the Reactor in functioning are presented as the emptying of gases produced in the pyrolysis by means of the biomass feeding system, the block of the thread of biomass feeding, the inert material sintering in the bed, etc. The possible causes are described. Thus it, the first ones could be solved, either by the reduction of the height of the inert bed, or by the increase of the wadding percentage of the thread, among others. Theese results of the exploratory tests make possible the steady work of the plant, greater knowledge of the phenomena that occur during the fast pyrolysis in fluidizated bed, as well as the establishment of adjusted levels for the identified independent factors during the remaining experimental works.

Keywords : reactor; fluidizated bed; fast pyrolysis; biomass; bio-oil.
