摘要
用常压液相炭化法制备中间相沥青 ,并用熔融法检验中间相沥青的可纺性。研究了汽油裂解残油和催化裂化重柴油参混比的不同对中间相沥青的制备速率、产率、中间相含量、显微结构以及可纺性的影响 。
Mesophase pitch was prepared by atmospheric carbonization in liquid phase, and melting method was employed to test its properties in spinning. The effects of different ratios of cracking gasoline residue and heavy diesel oil from catalytic cracking on formation rate of mesophase pitch, yield, content of mesophase, microscopic structrue and spinning properties were studied. The best ratio has been derived.
