In pyrolysis, lignin, cellulose, and semicellulose, the main com ponents of biomass are quickly thermochemically decomposed in seconds to form smallmolecule compounds, in which about 50% of the volatiles can be condensed to form biooil. The carbon content of biooil ranges from 30 to 50%, and the high heating value (HHV) is about 15 MJ kg−1.
