Hydrodeoxygenation of pyrolysis bio-oils from ablative flash pyrolysis of straw: an analytical study

Popis výsledku v původním jazyce

Pyrolysis bio-oils have a promising potential to be used as biofuels or as a source of valuable oxygen-containing chemicals. The efficient use of bio-oils is limited by their undesirable properties that arise especially from the high contents of oxygen and water. Thus, an appropriate upgrading is required for the further use of bio-oils. To optimize such an upgrading process, a detailed knowledge of the chemical composition of bio-oils and upgraded products is necessary. Here, we performed the hydrodeoxygenation (HDO) of pyrolysis bio-oils obtained from the ablative flash pyrolysis of straw at different reaction conditions using the sulphidic Ni-Mo/Al2O3 catalyst. Then, we performed the chemical characterization of the raw pyrolysis bio-oil (feedstock for the HDO) and liquid HDO products. Basic physico-chemical properties (density, viscosity, elemental composition, water content, calorific value, Conradson carbonisation residue, etc.) were measured to evaluate the quality of the obtained products. In addition, titration and GC-MS were used to evaluate the contents of main groups of bio-oil compounds including acids, sugar compounds, phenols and carbonyls to obtain more details about the composition of these products. The obtained results may further improve the understanding of the HDO of bio-oils from the lignocellulosic biomass which is a promising process for producing advanced biofuels for stationary and mobile applications.
