THE INFLUENCE OF CONDENSATION TEMPERATURE ON THE PROPERTIES AND COMPOSITION OF MISCANTHUS BIO-OIL

Popis výsledku v původním jazyce

Bio-oil properties and composition can be improved by the modification of the pyrolysis-vapours condensation-step just before the bio-oil is created. This improvement can lead to a decrease in water and acid content, and to an increase in the homogeneity of bio-oil. In this work, we studied the influence of the condensation temperature (5-100 °C) in the first condensation stage (cooler) of ablative fast pyrolysis on the composition of a miscanthus bio-oil. We carried out the analysis of physicochemical properties (density, viscosity, elemental composition, water content, micro Conradson carbonization residue and higher heating value) of seven bio-oils condensed at different temperatures. Volatile compounds were quantified by a GC-MS method; the sum of the main oxygenated groups (acids and carbonyls) in the whole sample was quantified by titration methods.
