dc.description.abstract | This study deals with a continuous process on a calcined dolomite operating at atmospheric pressure and by cofeeding
water for cost-effective upgrading of raw bio-oil at 400 °C and 500 °C. The distribution of carbon in the
feed to the product fractions (gas and upgraded bio-oil) and to the dolomite (as CO2 captured and coke) was
investigated with time on stream, as well as the evolution of the gas and the upgraded bio-oil composition. Acids
and high-molecular weight phenols were completely removed from the raw bio-oil for 0.5 h time on stream, with
the upgraded bio-oil being mainly composed of ketones (acetone, 2-butanone and cyclopentanones).
Chromatographic analyses of the reaction products were combined with analysis of the dolomite characteristics
by thermogravimetry and X-ray diffraction. The results are explained on the basis of possible reaction mechanisms
on the dolomite basic sites (CaO, Ca(OH)2 and MgO) and the extent of dolomite carbonation with
adsorbed CO2. Composition of the upgraded bio-oil makes it suitable for further catalytic valorization for obtaining
fuels and chemicals, such as H2 (by steam reforming) and aromatic hydrocarbons (by dual-stage hydrogenation-
cracking processes). | es_ES |
