摘要 废弃生物质生态安全利用是废弃物减量化与资源化的重点和难点。水热转化技术是近年来迅速发展的一种特别适合于处理高含水率原料的热转化技术,在废弃生物质无害化和高值化利用方面具有巨大潜力。以收录于CNKI和Web of Science索引库中(2000年1月—2019年12月)关于废弃生物质水热转化的2960篇文献(CNKI 600篇,Web of Science 2360篇)为数据源,利用CiteSpace 5.5知识图谱软件对作者、发文机构以及关键词进行分析,利用关键词聚类分析方法解析该领域研究的前沿热点和发展态势。分析结果表明,全球范围内废弃生物质水热转化发文量可分为缓慢发展期(2000—2007年)、快速增长期(2008—2016年)和小幅下降期(2017—2019年),其中农业废弃生物质水热转化的中英文研究论文均呈现增长态势;我国学者对废弃生物质水热转化研究的贡献较为突出,研究的重点集中在固体产物(特别是炭基材料)和液体产物(特别是生物油)生产及特性等方面;未来废弃生物质水热转化的研究热点为水热转化原料预处理、水热转化工艺条件、水热反应过程和水热转化产物高值化利用等方向。该研究可为水热转化技术在废弃生物质生态安全利用领域的产业发展提供参考。 The ecological safety has been the focus and difficulty in management of waste biomass by reduction and recycling modes.In recent years,hydrothermal conversion technology has been developed rapidly,which is suitable for the treatment of waste biomass with high moisture content.In addition,it has great potential for the harmless treatment and high value-added utilization of waste biomass.In this study,2960 literatures were used as the data source,including 600 and 2360 from CNKI and Web of Science databases,respectively,from January 2000 to December 2019.CiteSpace knowledge mapping software 5.5 was used to analyze authors,institutions and key words derived from the data source.Then the hot spots and development trend of this technology were analyzed based on the key words cluster analysis method.The results show that in terms of the global number of literatures on hydrothermal conversion of waste biomass,there were three stages between 2000 and 2019,including slow growth period(from 2000 to 2007),rapid growth period(from 2008 to 2016),and slight decline period(from 2017 to 2019).In the past two decades,among all the literatures the Chinese and English literatures associated with hydrothermal conversion of agricultural waste biomass kept growing.Chinese scholars have made outstanding contributions to the study of hydrothermal conversion of waste biomass.The research hotspots were focused on the production and properties of solid products(especially carbon-based materials)and liquid products(especially bio-oil).It is predicted that the developing trend of this technology will concentrate on the pretreatment of raw materials,technological conditions,reaction process,and the high value-added utilization of products.This study could provide references for the industrial development of hydrothermal conversion technology used in the field of ecological and safe treatment of waste biomass.
