摘要
生物质能作为零碳可再生能源,在应对气候变化、保障能源安全及推动可持续发展中具有重要的战略意义。通过生物质热化学转化技术定向制备清洁燃料与高值化学品,成为实现生物质高效利用的关键路径。当前该领域的研究虽在工艺优化、催化剂开发和产物调控方面取得了进展,但对领域动态演变的系统性梳理仍显不足。为系统梳理国内该领域的研究现状、热点及发展趋势,基于CiteSpace软件对近10年间生物质热化学转化领域的中文文献数据进行了可视化分析。通过构建知识图谱,揭示了我国该领域研究热点聚焦于热解/气化技术优化、催化裂解机理探究和生物质协同转化,核心方向呈现从基础工艺向产物提质与系统集成演进的阶段性特征。未来需强化多技术耦合机制,开发高效可再生复合催化剂,融合人工智能优化反应路径与碳足迹评估体系,深化超临界热解、微波热解等新兴工艺机理,平衡环境友好性与经济性,推动生物质热化学转化向智能化、高效化跨越式发展。
As a zero-carbon renewable energy source,biomass energy is of strategic significance in combating climate change,guaranteeing energy security and promoting sustainable development.The targeted preparation of clean fuels and high-value chemicals by biomass thermochemical conversion technology has become a key pathway for realizing the efficient utilization of biomass.Although the current research in this field has made progress in process optimization,catalyst development and product regulation,the systematic review of the dynamic evolution of the field is still insufficient.In order to systematically sort out the current hotspots and development trends of this field in China,based on the CiteSpace software,the Chinese paper data about biomass thermochemical conversion in the past decade was visualized and analyzed.Through the construction of knowledge map,it is revealed that the research hotspots in this field in China are focused on optimizing pyrolysis/gasification technology,exploring catalytic cracking mechanism and biomass synergistic conversion.The core direction presents a phased evolution from the basic process to product quality improvement and system integration.In the future,it is necessary to strengthen the multi-technology coupling mechanism,develop highly efficient and renewable composite catalysts,integrate artificial intelligence to optimize the reaction path and carbon footprint assessment system,deepen the supercritical pyrolysis,microwave pyrolysis and other emerging process mechanisms,balance the environmental friendliness and economy,to promote the biomass thermochemical conversion towards intelligent and efficient leapfrog development.
