Title:
PYROLYSIS METHOD FOR PLANT BIOMASS
Document Type and Number:
WIPO Patent Application WO/2012/090369
Kind Code:
A1
Abstract:
An object of the present invention is to provide a convenient method for extracting a useful organic compound from plant biomass. According to the present invention, a method for pyrolyzing plant biomass comprising a 1st heating step in which biomass is heated at a 1st heating temperature and a 2nd heating step in which either a gasified product or a biomass residue obtained in the 1st heating step is heated at a 2nd heating temperature higher than the 1st heating temperature is provided. The method of the present invention makes it possible to extract useful organic compounds such as phenols from plant biomass with heat treatment alone.
