► Lignin pyrolysis proceeds in the gas and solid/liquid phases in heating at 600 °C. ► The gas- and solid/liquid-phase reactions are explainable with the temperature-dependent reactions, that is, devolatilization (200–400 °C), methoxyl group-related reactions (>450 °C) and intermediates gasificat...
