摘要
运用远红外傅立叶变换光谱、超导核磁、光栅发射光谱、元素分析、X射线荧光光谱等分析测试手段,对烟煤和白煤的基本结构单元进行了表征。研究表明,白煤骨架中的芳环聚合度比烟煤大,碳支链较烟煤少;而且在白煤骨架中部分三维碳骨架中可能存在C—O—Si—O—C化学键。研制出了型煤净洁剂,将其与白煤粉、烟煤粉进行拌合,冷压后制成的型煤着火点降低,燃烧速度加快,不仅燃煤效率提高了20%,而且消烟除尘效果已达排放标准,有害气体二氧化硫降低了48%。
The main basic units of coal structure had been studied by FTIR, ^13C NMR, X-ray fluorescence spectra and other analytic methods. The experimental results show that anthracite contains more benzenoid polycireles and less carbon branch chains than bituminous coal. It is also found that there probably exists C--O--Si--O--C structure in the three-dimensional carbon skeleton structure of the anthracite. The cleaning agent was designed. The cleaning agent, anthracite and bituminous coal were mixed together, and compressed to coal briguette for the kiln use. The results indicate that burning point decreases, burning velocity increases obviously and burning efficiency increases 20% than before. Furthermore, not only the efficiency in removing smoke and dust was improved and reached the country standard, the concentration of hazardous sulphur dioxide was also decreased by about 48%.
