Pinewood oxidative flash pyrolysis has been performed in continuous mode in a pilot plant provided with a conical spouted bed reactor, at 500 ºC. The influence of oxygen addition on the pyrolysis yields and product properties has been studied. Product analysis has been carried out on line by means of chromatographic methods. Gas and water amounts are increased during oxidative pyrolysis, whereas combustion reactions lead to a decrease in char and bio-oil amounts. High liquid...
