摘要/Abstract

摘要： 以石油基中温沥青为原料，经过热聚合?氢化?热处理制备中间相含量大于80%的广域流线型的中间相沥青，对处理过程中沥青的组分和结构变化进行了表征，对低温长时间和高温短时间处理对中间相沥青形态的影响规律进行了探讨. 结果表明，原料通过热聚合，沥青中的甲苯不溶物含量和芳环数提高；再经过加氢改性，沥青分子中的脂环烃增加，流动性改善；最后经高温短时间或低温长时间热处理形成含侧链或环烷结构的稠环芳烃分子，低温长时间处理更有利于中间相分子充分发展，易获得广域流线型的中间相.

Abstract: The petroleum asphalt was used to prepare the mesophase pitch through three steps treatment including polymerization, hydrogenation and heat treatment. The mesophase content in the obtained product is more than 80%. The composition and structure of asphalt in the three-step process were characterized. Besides, the influence of heat treatment conditions, like low temperature with a long time and high temperature with a short time, on mesophase pitch morphology was investigated. The results showed that the content of toluene insoluble and the number of aromatic rings in the asphalt were improved by thermal polymerization. After modified by hydrogenation, the alicyclic hydrocarbons in the asphalt molecules was increased and the mobility was improved. Finally, after thermal treatment, the polycyclic aromatic molecules were formed with side chains or naphthenic structure. The treatment by low temperature with long time was favorable to the development of mesophase molecules and obtaining wide-area streamlined mesophase.

Key words: petroleum pitch, thermal polymerization, hydrogenation, heat treatment, mesophase pitch
