Abstract

The present invention discloses a method for producing biocrude and bioactive substances from microalgae biomass, comprising the steps of: mixing and stirring dry microalgae biomass with water and an acid catalyst; heating the mixture at high pressure at a temperature and time based on each individual species or processing the biomass mixture in a colloidal mill (202) with solvent; separating lysed algae cells into non-polar extracts from water-soluble extracts via vacuum filtration (102); washing the lysed algae cells and non-polar extracts with organic solvents; separating the organic solvent mixture, which comprises ethanol and long-chain fatty acids, from the remaining biochar via vacuum filtration (102); and separating the ethanol from the fatty acids via distillation or rotary evaporator (204) to extract bio-oil.
