鉴于利用玉门炼油厂原料(一种石蜡基混合原油)的减压渣油和减压渣油的溶剂脱油沥青不能直接生产出合格的道路沥青,根据优质道路石油沥青性能对组成分子的基本要求,利用多元调合法间接试制道路石油沥青,研制出了能生产出包括中石化集团公司2号高等级道路沥青(Q/SHR004-1998)在内的多种牌号道路沥青配方.初步探讨了在减压渣油中调入适量催化裂化油浆,并经溶剂脱沥青工艺直接生产道路沥青的可行性.试验结果表明,在脱沥青油收率增加的同时,脱油沥青的道路石油沥青性质明显改善,因此可优化炼油厂的工艺组合.研究方法对于加工石蜡基或非石蜡基原油的炼油厂具有指导意义.

Many specifications of paving asphalts are closely related to their colloidal stability, which is, however,determined by their exact chemical compositions. The Yumen vacuum residue (YVR), the bottoms of a paraffinic crude oil is unfit for the production of highway paving asphalts directly, Neither are the de-oiled asphalts of the YVR. In this research a blending method and an optimal process of solvent de-asphalts are adopted to investigate the feasibility of formulating highway-paving asphalts from YVR. Results show that highway paving asphalts are formulated by blending solvent de-oiled asphalts with one or more of the materials including YVR, decanted oil from FCC process, and furfural extracts from lubricating base stocks. Further investigations indicate that adding oil decanted from FCC process to the solvent de-asphalting process can increase the de-asphalted oil production, improve the de-oiled asphalts quality, and thus optimize the refinery processes. The methodology of this research can be extended even to refineries processing non-paraffinic crude oils.
