| Outline of Final Research Achievements |
Better understanding of the molecular mechanisms involved in wood pyrolysis would provide insights into the upgrading of various pyrolysis-based technologies, which include carbonization, gasification and fast pyrolysis. In this project, we studied the molecular mechanisms of wood pyrolysis under the focus of heterogeneity of cellulose and cell wall, which consists of cellulose crystallites surrounded by lignin-hemicellulose matrix. As a result, we clarified the roles of reducing ends in cellulose pyrolysis, radical chain mechanisms in lignin pyrolysis, interactions between lignin and hemicellulose/cellulose, gas-forming mechanisms from cellulose and so on.
