Understanding the migration and conversion of nitrogen in wood-based panels during pyrolysis is crucial for transforming N-containing species into valuable products. This review summarizes methods for examining N evolution and analyzes the wood-adhesive interactions impact on pyrolysis. The distribution and evolution of N-containing species in gas, liquid, and char during WBPs pyrolysis are investigated in recent studies, with comparison between heating sources and proposing converting pathways for value-added chemicals and carbon materials.
Understanding the migration and conversion of nitrogen in wood-based panels (WBPs) during pyrolysis is fundamentally important for potentially transforming the N-containing species into valuable material-based products. This review firstly summarizes the commonly used methods for examining N evolution during the WBPs pyrolysis before probing into the association between the wood and adhesives. The potential effects of wood-adhesive interaction on the pyrolysis process are subsequently analyzed. Furthermore, the controversial statements from literature on the influence of adhesives on wood pyrolysis behavior are discussed, which is followed by the detailed investigation into the distribution and evolution of N-containing species in gas, liquid and char, respectively, during WBPs pyrolysis in recent studies. The differences in N species due to the heating sources (i.e. electrical heating vs microwave heating) are particularly compared. Finally, based on the characteristics of staged pyrolysis, co-pyrolysis and catalytic pyrolysis, the converting pathways for WBPs are proposed with an emphasis on the production of value-added chemicals and carbon materials, simultaneously mitigating NOx emission.
