| 喹啉不溶物是煤焦化過程中帶入的固體不溶物,煤瀝青中喹啉不溶物對于煤瀝青的深加工具有重要作用。研究了以溶劑沉降法脫除煤瀝青中喹啉不溶物,考察了溶劑、沉降溫度以及沉降時間對凈化瀝青QI含量和收率的影響。結(jié)果表明,在一定范圍內(nèi),沉降溫度越高,越有利于QI的脫除,當(dāng)溫度達到180℃以后對沉降的影響較;以輕油與重油按質(zhì)量比3:9調(diào)至的混合溶劑較單純的溶劑油有更好的沉降效果;沉降時間越長,QI脫除率越高,凈化瀝青的收率越低。 |

| 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 . |
