柴油蜡晶的组成与微观形貌的研究

Study on the Coposition and Microstructure of Wax Crystal of Diesel

本文采用GC—MS法分析了柴油蜡晶的化学组成及含量；并利用场发射扫描电镜观察蜡晶微观形貌．研究结果表明：0#柴油蜡晶主要由C11—C25的正构烷烃组成；通过对柴油在冷滤点的显微形态观察表明，蜡晶主要的微观特征为三维网状结构连成的圆盘状结构．

The contents and carbon number distribution of n-paraffin wax of 0#diese fuel in Xinjiang were determined by GC-MS;The change of microscopic shape is researched by the Field Emission Scanning Electron Microscope.Results showed that wax crystal was mostly composed of n-paraffin with carbon number from 11 to 25; The main microscopic characteristics of wax crystal is connected into a three-dimensional network structure of disk-like structure.
