摘要
煤直接液化工艺生产的中温溶剂油和将中温溶剂油加氢后的烷基油(1211)具有良好的热稳定性,适宜作为LQC320精制矿物油型有机热载体(导热油)馏分,为有机热载体的生产提供了一条新的途径。通过分析不同来源馏分的馏程和烃类组成对馏分热稳定性的影响,并考察馏分调和后对热稳定性的影响以及抗氧剂对中温溶剂油和1211烷基油热稳定性的影响后发现,环烷烃和芳烃的热稳定性较好,链烷烃的热稳定性较差;通过不同馏分之间的调和,可以使馏分的馏程和烃类组成分布更加合理,从而提高热稳定性;胺型抗氧剂能赋予煤液化生产的矿物油型有机热载体更好的热稳定性。
The alkyl oil （1211） with middle-temperature solvent oil and after the hydrogenation of medium temperature solvent oil during direct coal liquefaction process has great stability, was suitable for the fraction of LQC320 refined mineral heat transfer fluids, and provided a new way for the production of heat transfer fluids. According to analysis of the effects of distillation range and hydrocarbon composition of different fractions on stability, investigated effects of reconcile on thermal stability and effects of antioxygen on stability of middle-temperature solvent oil and 1211 alkyl oil, the authors found that cycloalkanes and aromatics had great thermal stability, alkane had poor thermal stability, reconciling different fractions could make the fraction range and hydrocarbon composition become more reasonable and improve the thermal stability, and the amine-type antioxidant could give higher thermal stability to the mineral oil heat transfer fluids production with coal liquefaction.
