This paper describes a Fast Continuous Pyrolysis of Biomass Process that is being improved in a University of Campinas Plant Pilot, rated at a capacity around of 100 kgh-1 of biomass. The process utilizes a deep bubbling fluidized bed technology and Bio-Oil and Charcoal recovery system [1]. The feedstock’s used for these studies were elephant grass and sugarcane bagasse, which were dried up to equilibrium moisture content (more less 10 % humid basis). The Figure 1 show a photo of the rapid pyrolysis plant. Figure 1. Photo of the rapid pyrolysis plant A CSFB Simulator [2] is used to obtain several results computer, which include: concentration and mass flow profiles of gas components, concentration, mass flow and particle size distribution profiles of solids species throughout the bed, composition of the exit streams, entrainment and elutriation parameters and others details, to each experimental test condition. On the other hand, a could flow mode ls is used to examine the fluid dynamic behavior of bed inert, charcoal and feedstock’s into a range of fluidization regimes. High yields of charcoal (maximum between 15 and 20 % dry basis for this technology) are produced from low gas superficial velocity (proximate at the minimum fluidization velocity of 0,1ms-1) an
