Аннотация:The fractional and chemical composition of bio-oil and its gasoline fraction, obtained by hydrothermal
liquefaction of Arthrospira platensis biomass, was studied. The bio-oil yield was 34.6%, the heat of combustion of bio-oil was 33.4 MJ kg–1, and the gasoline fraction yield was 28.8%. The content of carbon and hydrogen in the gasoline fraction of the bio-oil is appreciably higher than in the initial bio-oil, and the calorifi c value of the gasoline fraction is 3.87 MJ kg–1 higher than that of the initial bio-oil. With respect to the carbon and hydrogen content, the gasoline fraction of the bio-oil is close to motor fuels, diff ering from them in the higher content of nitrogen, oxygen, and sulfur. Fractional distillation of bio-oil decreases the content of high-molecular-mass condensed compounds in the product.
