摘要
对利用新疆重质混合原油生产的减压渣油作为基质沥青制备高等级道路沥青进行了研究。考察了低硫石蜡基原油(A)和含硫环烷-中间基原油(B)的掺炼比对基质沥青四组分组成的影响,减压渣油软化点与基质沥青四组分组成的关系,以及添加剂对改进沥青性质的作用。由此得出原油(B)的合适掺炼量,减压渣油软化点的控制范围和优化的生产工艺条件,调合出了符合GB/T18150-2000和JTGF40-2004要求的高等级道路沥青。
Vacuum residue used to prepare premium grade road sulfur paraffin base crude （A） and softening additives produced point of vacuum and adding under the tempe produced asphalt. from th The eff sulfur containing e distillation of Xinjiang mixed crude oils could be ects of the blending ratio of two crude oils, low naphthene-intermediate base crude （B）, and the residue on the SARA content of base asphalt were investigated. rature on improving asphalt quality were studied as well. Finally optimal requirements of GB/T18150- The types , the asphalt crude B blended ratio and optimum processing conditions met the 2000 and JTG F40--2004 premium grade road asphalt.
