摘　　要：为了对半焦中矿物质实现有效的分离,以便后续的高效洁净转化利用,以神府原煤及3种热解半焦为样品,采用显微镜观察、等离子体低温灰化、气相色谱红外光谱联用仪、X射线衍射等方法对原煤及半焦样品中的矿物质进行了分析,在此基础上,研究了样品中主要矿物的种类、嵌布特征,分析了它们在热解前后的主要变化。To separate minerals in semi-coal effectively and use efficiently, Shenfu raw coal and three pyrolysis semi-cokes were used as in the study, and minerals of raw coal and semi-cokes were analyzed using microscope, plasma low temperature asher, GC-FTIR combination technology and XRD. Based on this, the main species of minerals and dissemination characteristics were investigated to analyze the main changes before and after pyrolysis.
