This paper describes fast pyrolysis process from a continuous air fluidized bed reactor utilizing sugarcane bagasse, trash, and elephant grass. The experiment was conducted by UNICAMP (FEAGRI and NIPE) and the Copersucar Technology Center-CTC in Piracicaba-SP, Brazil. The process utilizes a atmospheric bubbling fluidized bed in pilot-plant-scale, combined with conventional systems to recovery of solids (pulverized charcoal) and Bio-Oil (pyrolysis liquid). The fast pyrolysis system was designed and built by UNICAMP, Copersucar Technology Center, and Termoquip Alternative Energy Ltda. The project is currently underway in its final phase to assembly and to adjust the experimental and instrumental arrangement. The experimental strategy will allow us to optimize the studied parameters. The mathematical modelling will allow to obtain the temperature, product concentration, and velocity profiles, using a computational fluidodynamics technique named CFD to each experimental test condition. The ultimated goal of this research project is to develop alternative technologies to economically produce charcoal and Bio-Oil. A feasibility study, considering technical and environmental aspects will also be conducted.
