In the pyrolytic gasification of woody biomass, cellulose decomposes into levoglucosan, which is subsequently gasified via radical chain mechanisms. However, due to the stability of levoglucosan, its gasification requires temperatures exceeding 800°C. Such high temperatures lead to the formation of coke and clinker, significantly reducing gasifier operational efficiency. To address this issue, a substantial reduction in gasification temperature is essential. We explored the potential application of microwave plasma as a solution.
