RESUMO

The energy content of biomass can be exploited by direct combustion or after conversion by physical, biological and thermochemical processes. Among the thermochemical processes there is the pyrolysis that is an attractive process because it provokes the conversion of solid biomass into liquids products. Such conversion presents many advantages in transport, storage, handling, retrofitting, combustion and flexibility in production and marketing. The goal of this work was to build and operate a bench scale fluidized bed reactor to convert sugarcane bagasse into liquid products by fast pyrolysis. The reactor design presents 0,095 m internal diameter and fine sand was used as inert material for the fluidized bed. A new hopper to control the continuous feed of biomass in the reactor and an isokinetic sampling device to quantify the products obtained in the process. An experimental methodology was written for tests with biomass. Experimental essays carried out with fluid catalytic cracking and water injection in the stream in order to verify these effects in the process. Temperature and static height of the bed was also considered in this study. The static height of the bed and the temperature were the variables more important, requiring special attention in the conversion process
