针对西部发展对高等级道路沥青的市场需求,从塔河原油及其焦化蜡油的性质分析入手,对掺入不同比例焦化蜡油的塔河原油进行减压蒸馏技术研究,分析其不同馏程段渣油性质,对其减压渣油生产高等级道路的调和沥青性质进行探索研究.结果表明,塔河原油掺入焦化蜡油减压蒸馏,可提高渣油闪点,降低其软化点、蜡含量,适度降低最终沥青产品的PI值,焦化蜡油掺入比例以15％为最佳.“,”For the development of the market demand of high grade road asphalt in the west China,the vacuum distillation of Tahe crude oil mixed with different proportions of coker gas oil is carried out from analysing the properties of Tahe crude oil and coker gas oil.The properties of different distillation residue are analyzed.The properties of high grade road blending asphalt produced with the vacuum residue are also explored.The results show that the vacuum distillation of Tahe crude oil mixed with the coker gas oil can improve the flash point of residual oil and reduce the softening point and wax content.There is a modest decrease in PI value of the final asphalt products.The optimal content of coker gas oil is 15％.
