煤中碳、氢和氮含量测定的操作要点

摘要

煤是我国重要的能源物质,关于煤类型的研究对提高煤炭利用率,节能环保,合理使用资源具有重要意义.其中,通过技术性手段对煤的各项指标进行测定,是研究煤的种类及加工途径的重要方式.基于此,主要通过碳氢氮分析仪对煤中的碳氢氮进行测定,重点阐述测定原理以及在测定过程中需要注意的问题.%Coal is an important energy substance in our country.The research on coal type is of great significance for improving coal utilization,energy conservation and environmental protection,and rational use of resources.Among them,the technical means to measure the various indicators of coal,is an important way to study the types of coal and processing methods.Based on this,this paper mainly uses the hydrocarbon-nitrogen analyzer to measure the hydrocarbon nitrogen in the coal,and focuses on the principle of the determination and the problems that need attention in the determination process.
