塔河四区混合原油制取重交通道路沥青的研究 总被引:3,自引:2,他引:1
根据塔河四区混合原油的性质 ,进行了生产 AH-90重交通道路沥青的可行性研究。研究结果表明 ,>4 1 0℃、>4 1 2℃减压渣油符合 AH-90重交通道路沥青指标要求 ,但是 ,随着蒸馏温度的提高 ,1 5℃延度值下降较大 ,生产控制范围窄 ,操作弹性小 ,给生产带来了一定困难。在一定针入度的减压渣油中 ,加入定量的糠醛抽出油 ,各项性能指标完全满足AH-90重交通道路沥青指标要求 ,1 5℃延度和薄膜烘箱试验后 2 5℃延度值均大于 1 0 0 cm。 相似文献

The highly viscous crude oil from Shuguang No.1 zone of Liaohe oifield features high density,high viscosity and low wax content.It contains no gasoline fraction and its diesel oil fraction yiled is only 7.19%,which belongs to the low sulfur naphthenic stocks crude oil.Its heavy fraction is not suited for producing lubricating oil.Its heavy oil,whick contains more resins nd asphaltens and less wax,is not an ideal feedstock for catalytic cracking ,but is the ideal raw material for producing high-grade paving asphalt.Now this highy viscous crude oil is used as fuel oil after being emulsified in Liaohe oilfield,but its viscosity is so hight tha it cannot be atomized uniformly and burned completely,resuting not only in waste of oil resource but also in reduction of economical benefit.To make full use of this oil resource and alleviate the shortfall of high grade paving asphalt in China,various brands of asphal meeting Q/SHR003-1998 and ESSO specifications were developed by blending vaceuum residue of the said oil and a blending compo-net which are rich in aromatics and deficient in wax.The impct of blending component on proerties of blended ashalt has been investigated and road perfomances of these blended asphalts were studied.The labroatory test results show that the blended asphalts have good road performance and antiaging property. 相似文献
