[1] Hydrothermal liquefaction of arthrospira platensis for bio-oil production and study of chemical composition for bio-oil and its gasoline fraction / A. V. Grigorenko, Y. I. Kostyukevich, N. I. Chernova et al. // Russian Journal of Applied Chemistry. — 2019. — Vol. 92, no. 11. — P. 1480–1486. 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. Keywords: hydrothermal liquefaction, bio-oil, biofuel, microalgae, autoclave reactor, high-resolution mass spectrometry. [ DOI ]
