从生物质中获得能源具有可再生性。纤维素、木质素是自然界中分布最广最重要的资源之一,占植物界碳含量的50%以上。超临界水气化是纤维素、木质素气化的有效手段。探讨了纤维素、木质素气化过程及影响因素;根据纤维素、木质素的气化路径,总结出纤维素、木质素气化的重要反应类型及机理及其典型动力学模型,及各类催化剂的催化机理。最终提出了纤维素、木质素气化发展方向,为超临界水气化纤维素、木质素提供参考。
Renewable energy from biomass. Cellulose and lignin are one of the most widely distributed and most important resources in nature, accounting for more than 50% of the carbon content in the plant community. Supercritical water gasification is an effective means of gasification of cellulose and lignin. Based on the gasification path of cellulose and lignin, the important reaction types and mechanisms of cellulose and lignin gasification and their typical kinetic models were summarized, and the types and influencing factors of cellulose and lignin gasification were also discussed. Catalytic mechanism of catalyst. Finally, the development direction of cellulose and lignin gasification is proposed, which provides a reference for the supercritical water gasification of cellulose and lignin.
