Soot quantification during bio-oil thermal conversion

This work investigated the quantification of soot in the producer gas during bio-oil thermal conversion process. a laser extinction device was specially developed based on beer-lambert law. a calibration of the measurement was performed with acetone as one of the model compounds of bio-oil. the pyrolysis of acetone revealed a maximal soot production at 1200°c,at this temperature the model was developed based on the soot volumetric fraction and extinction coefficient. three sets of experiments were carried out under a large range of temperature (from 1000 to 1400°c) and under different atmospheres: inert atmosphere (pyrolysis),excess of steam (gasification) and with presence of oxygen (partial oxidation). the results showed that temperature and gasifying agents were strong influence on the soot formation and oxidation mechanisms.
