摘　　要：以催化裂化柴油为原料,合成了缩合多环多核芳烃(COPNA)树脂。在催化裂化柴油催化剂交联剂质量比为1∶0.1∶0.35、反应温度为140℃、反应时间为14 h的最佳交联条件和固化温度为350℃、固化时间为150 min的固化条件下,中等缩合度缩合多环芳烃(B-COPNA)树脂和热固性缩合多环芳烃(C-COPNA)树脂收率分别为73.22%和56.14%。采用气相色谱-质谱联用与傅里叶变换红外光谱研究发现,催化裂化柴油存在不含长烷基侧链的多环芳烃,空间位阻小,适合作为合成COPNA树脂的原料。采用热重分析仪研究树脂的热行为,发现合成的B-COPNA树脂和C-COPNA树脂的残炭分别为44.26%和45.17%。反应后柴油收率为41.38%,其饱和烃质量分数从34.15%提高至83.11%,柴油十六烷指数从33.13提高到42.39。In this paper,FCC diesel was directly used as raw material to synthesize condensed polycyclic polynuclear aromatic hydrocarbon(COPNA)resin.Under the optimal cross-linking conditions of a catalytic diesel,catalyst and crosslinker mass ratio of 1∶0.1∶0.35,a reaction temperature of 140℃,a reaction time of 14 h,and a curing temperature of 350℃,a curing time of 150 min,the yields of moderate condensation polycyclic aromatic hydrocarbon(B-COPNA)resin and thermosetting condensation polycyclic aromatic hydrocarbon(C-COPNA)resin were 73.22%and 56.14%,respectively.The results of gas chromatography-mass spectrometry(GC-MS)and Fourier infrared spectroscopy(FT-IR)showed that FCC diesel was rich in polycyclic aromatic hydrocarbons without long alkyl side chains and had small steric hindrance,which was suitable as a raw material for COPNA resin.The thermal behavior of the resin was studied by thermogravimetric analyzer,and it was found that the carbon residue rates of the synthesized B-COPNA resin and C-COPNA resin were 44.26%and 45.17%,respectively.After the reaction,the yield of diesel was 41.38%,the content of saturated hydrocarbon increased from 34.15%to 83.11%,and the cetane number of diesel increased from 33.13 to 42.39.
