Research Abstract

This study was dedicated to the clarification and modification of biomass pyrolysis mechanism under different conditions with the newly proposed parameter index based on structural analyses of cellulose, particularly cross-linking behavior. We aimed to further develop the pyrolysis/gasification process by considering the combination of pretreatments at low temperature with simple reforming methods at high temperature to selectively obtain valuable products.
