Abstract

A bio-oil was prepared from planktonic algal biomass via thermochemical liquefaction with a NaOH catalyst. The effects of reaction conditions, including temperature, time, and the ratio of biomass to solvent, on the liquefaction yield were investigated. The liquefaction yield initially increased and then decreased with increasing temperature and reaction time. The maximum yield (61.6%) was observed after liquefaction at 300°C for 30 min with 0.2 mol/L NaOH as a catalyst and a biomass to solvent ratio of 1:10. The chemical components of the obtained bio-oil were analyzed via gas chromatography/mass spectrometry, with results indicating that the algal bio-oil was composed of furan, phenol, acid, and ester derivatives.
