| 喹啉不溶物是煤焦化过程中带入的固体不溶物，煤沥青中喹啉不溶物对于煤沥青的深加工具有重要作用。研究了以溶剂沉降法脱除煤沥青中喹啉不溶物，考察了溶剂、沉降温度以及沉降时间对净化沥青QI含量和收率的影响。结果表明，在一定范围内，沉降温度越高，越有利于QI的脱除，当温度达到180℃以后对沉降的影响较小；以轻油与重油按质量比3：9调至的混合溶剂较单纯的溶剂油有更好的沉降效果；沉降时间越长，QI脱除率越高，净化沥青的收率越低。 |

| Quinoline insoluble coal coking process into the solid insoluble quinoline insoluble in the deep processing of coal tar pitch coal tar pitch has an important role . Settlement Removal of quinoline insolubles in coal tar pitch solvent , of solvent , the settlement of temperature and deposition time on the purification asphalt QI content and yield . The results showed that , within a certain range , the settlement the higher the temperature , the more conducive to QI removal of the small settlement , when the temperature reaches 180 ° C ; raised the light oil and heavy oil mass ratio 3:9 mixed solvent have a better settlement than the pure solvent oil ; the longer settling time of QI removal rate is higher , the lower the yield of clean asphalt . |
