Viscosity reduction of coal tar from fluidized bed pyrolysis

State Key Laboratory of Clean Energy Utilization, Zhejiang University, Hangzhou 310027, China

摘要

摘要: 对循环流化床热电气焦油多联产热解所得煤焦油流动性差的问题采取了一系列的降黏研究。通过X射线衍射测试可以排除室温下蜡结晶影响煤焦油黏度的可能,对比了煤焦油和煤沥青的黏度和族组分差异,考察了喹啉不溶物对软化点的影响,结果表明,采取馏分油降黏是合理的。分别添加四种馏分油对煤焦油进行了降黏实验,通过色谱质谱联机分析馏分油的成分,认为既含亲水基又含憎水基的分子具有很好的降黏效果,而且含量越多降黏效果越好。通过添加四种单组分化合物的降黏实验和分析,进一步验证了所得到的降黏理论,而且可以判断同时含有亲水基和憎水基的分子降黏效果优于只含憎水基不含亲水基的分子。

Abstract: For the poor fluidity of coal tar generated from circulating fluidized bed polygeneration system, a series of research was carried out to decrease the viscosity. Through the analysis of X-ray diffraction, the possibility that the wax crystal increases the viscosity at room temperature was excluded. The viscosity and contents between coal tar and coal tar pitch were compared, and the impact of quinoline insoluble on the softening point was also investigated. The results reveal that it is reasonable to employ the distillates to decrease the viscosity of coal tar. Four kinds of distillates were blended in the coal tar to improve the fluidity, and the composition of the distillates was gotten through the GC-MS analysis. It is concluded that the molecule which contains both hydrophilic groups and hydrophobic groups possesses a great effect on the viscosity reduction, and the more the amount, the better the viscosity reduction. Four kinds of mono-component additives were tested, and the theory was verified. For the viscosity reduction, the molecule with both groups is better than that with only hydrophobic groups.
