Sequential Hydrothermal Liquifaction (SEQHTL) for Extraction of Superior Bio-Oil and Other Organic Compounds from Oleaginous Biomass

摘要

Methods of producing bio-fuel and other high-value products from oleaginous biomass (e.g. algae biomass) are provided. The two-step methods use a first step of subcritical water extraction of the biomass at low temperatures to produce polysaccharides and other high value products of interest, followed by, ii) hydrothermal liquefaction of remaining solid biomass at high temperatures to produce bio-oil.

主权项

1. A process for obtaining polysaccharides from oleaginous biomass comprising
heating a mixture of oleaginous biomass and an aqueous medium to a temperature in the range of from 155 to 165° C.; maintaining said mixture at said temperature for a period of time of from 15 to 25 minutes; then recovering polysaccharides released from said oleaginous biomass from said mixture.
