Abstract

The first phase of this project aims to carry out a technical evaluation for the production and commercialization of the products obtained by fast pyrolisis, principally bio-oil, from renewable national raw materials of vegetable origin (vegetable biomass). The Bioware pyrolisis process is versatile and uses technology of fluidized bed reactor on a pilot plant scale with a nominal capacity of 100 kilos per hour of polydisperse biomass to heat and devolatize rapidly the material particles, with the products of the pyrolisis (gases, vapors and pulverized solids) swept along by the same effect that produces the fluidization gas. In its first phase, the project envisages the implementation of three groups of tasks aimed at technical evaluation of the pyrolisis process. The first group involves improvements to the recovery and separation of liquids from the pyrolisis, from the burning of the pyrolisis gases and the measurement and control of operational and process variables (temperature, pressure, composition and escape of gases). The second group involves the technical evaluation of the pyrolisis process for the different operating conditions planned. The third group should study, in a preliminary way, the socioenvironmental impact of the technology based on the results obtained for the different operating conditions planned. (AU)
