摘要：
Hydrothermal liquefaction (HTL) of microalgae biomass over an aluminum oxide catalyst with an isomerization component in the neutral and sulfated forms was studied. Gas-chromatographic — mass-spectrometric analysis of the products led to conclusions about the effect of catalyst composition on the gasoline-fraction group composition of the processed bio-oil. The contents of isoalkanes and aromatic hydrocarbons increased whereas the concentrations of S-, 0-, and N-containing components decreased in the HTL products if a catalyst was used. The yield of water-soluble side products also decreased. Sulfated catalysts had greater effects than neutral catalysts on the group composition.
