国内生物质气化研究热点、演进与趋势分析

Analysis on hot topics, evolution and trend of biomass gasification research in China

为客观全面地分析我国生物质气化领域的发展脉络及研究动态,以近30年关于“生物质气化”的1722篇文献作为数据源,利用知识图谱软件对发文量、机构及关键词等进行文献计量与内容分析,解析该领域的前沿热点和发展趋势。研究表明:生物质气化发文量可分为初出萌芽期、蓬勃发展期和小幅下降期;我国生物质气化研究的热点集中在拓展生物质气化原料选择范围及优化气化技术、提高气化产物效率等方面,从重产率转向重社会效益。未来我国生物质气化的研究趋势为生物质原料外扩、气化反应机理、气化反应过程和气化产物高值化利用等方向。

In order to objectively and comprehensively analyze the development and research trends of biomass gasification in China, 1722 published articles on 'biomass gasification' in the past 30 years were used as the data source, and knowledge map software was applied to analyze numbers of articles, institutions, keywords, frontier hotspots and development trends. The results show that the research of biomass gasification can be divided into initial germination period, vigorous development period and slight decline period. The research hotspots of biomass gasification in China focus on expanding raw material selection range and optimizing gasification technology to improve efficiency, which changes from yield to social benefit. The future trend is focused on the expansion of biomass raw materials, gasification reaction mechanism, gasification reaction process and high value utilization of gasification products.
