摘　　要：以催化裂化油浆为原料,采用带程序升温控制多管井式坩埚炉和单管井式坩埚炉,及带有气流导向结构的反应器制备了高度有序中间相焦.重点考察了两种反应器结构对中间相有序生长的影响,依此探索气流导向作用对中间相焦有序生长的影响和中间相有序结构在高温处理过程中的发展变化.结果表明,原料在带有气流导向装置反应器中进行热聚合反应的过程中,在上升气流的引导作用下中间相微球之间实现有序融并、逐步发展为区域结构,由此可制备得到有序性发展良好的中间相焦.合理的煅烧温度制度可以使中间相焦有序结构与性能进一步完善和提高.With the FCC slurry as raw material, using multi-tube and single-tube well- crucible furnace controlled by programmed heating, and a reactor which contained pneumatic guide structure to prepare highly ordered mesophase coke. The experiment focuses on two reactor structures ~ influences on the ordered growth of mesophase, in accordance with the exploration of the impact on the ordered growth of mesophase coke by gas current and the changes of ordered mesophase structure in high temperature process. The experiment discovered that during the process of materials ~ thermal polymerization in the reactor with pneumatic guide structure, the mesophase spherule guided by the upcurrent melts orderly and gradually develops to domain structure. Thus it can prepare well-ordered mesophase coke which can be used to develop good intermediate phase differentiation burnt. Proper calcinations temperature would result in the fur- ther perfection and improvement of ordered mesophase coke structure and performance.
