FAST-PYROLYSIS OF BIOMASS RELATED MODEL COMPOUNDS: A NOVEL APPROACH TO EXPERIMENTAL STUDY AND MODELING
Fast pyrolysis is a potentially attractive method for converting biomass to a low energy-density liquid (bio-oil) that can be further upgraded for use as fuel. Currently there is no agreement concerning the reaction pathways and mechanisms for pyrolysis of any individual component of biomass. This …
