Abstract:
Fast pyrolysis of biomass is one of the most promising technologies for converting biomass to liquid fuels. In some applications pyrolysis oil can replace fossil heating oil however a bottleneck for the conversion is the heterogeneity and potential for phase separation of fast pyrolysis oils upon storage. So far there is no standardized method for studying phase separation tendency of pyrolysis oils. This study introduces Turbiscan as a tool for studying the phase separation phenomenon of pyrolysis oils. A well stored pyrolysis oil made of poplar wood was used in this study. The phase separation tendency of the bio-oil samples were observed for 24 hours at various temperature levels (25oC, 40oC and 60oC), and water was added to force phase separation of the bio-oils. Two techniques were used to study stability and phase separation tendency of bio-oils: Turbiscan Lab and Karl Fischer titration method. Stability and degree of phase separation was shown by Karl Fischer titration technique, whereby the diluted bio oils were found to be relatively well separated. The kinetics of the phase separation was investigated by Turbiscan technique.
