燃煤烟气脱硫脱硝脱汞研究文献计量分析

摘要

采用Web of ScienceTM核心引文数据库对1998—2017年收录的烟气脱硫脱硝脱汞相关领域的文献进行计量分析,以便准确掌握本领域的研究现状和前沿动态,有助于研究者了解该领域在全球发展的整体情况,明确未来的研究方向.结果表明:该领域的全球发文量总体呈持续快速上升趋势,无论是在科研机构还是研究学者方面,中国的发文量领先于世界其他国家,然而在高频次被引文献中中国的优势并不明显;该领域最有影响力的国际期刊为《Environmental Science & Technology》《Applied Catalysis B:Environmental》《Journal of Hazardous Materials》;烟气污染物脱除领域的热点为采用光催化、等离子体放电等手段,运用氧化还原反应原理将污染物氧化或还原后吸收脱除,此外SO2、NOx和Hg0的协同脱除和低温选择性催化还原技术也是该领域的研究热点.%Web of ScienceTM core citation database was used to econometrically analyze the articles about the removal of sulfur,oxynitride and mercury from flue gas that published from the year of 1998 to 2017,which could accurately grasp the research status and frontier dynamics in this field,and help researchers to understand the overall situation of global development in this field and define future research directions.The results indicated that the number of global publications in this field displayed a rapidly and steadily rising trend.No matter in the aspects of scientific research institution or research scholar,the publication amounts of China took a lead of other countries in the world.However,in the matter of high frequency cited articles,the advantage of China was not as obvious as that in article amounts.The most influential international journals in this research field were Environmental Science&Technology,Applied Catalysis B: Environmental and Journal of Hazardous Materials.The research hotspots in the field of flue gas pollutant removal were using the method of photocatalysis,plasma discharge and so on to oxidize or reduce pollutants through redox reaction and then remove them.Moreover,the simultaneous removal technology of SO2,NOx and Hg0 and low-temperature SCR technology were also research hotpots in this field.
