摘要/Abstract

摘要： 将10#建筑沥青的原料由单一的羊三木低凝减压渣油拓展为高凝减压渣油和催化油浆。在实验室内,用大港混合高凝原油减压渣油、催化油浆和低凝减压渣油为原料,按不同比例,在风量及氧化温度等不同试验条件下进行氧化反应,开展不同原料氧化生产10#建筑沥青的研制工作,依据GB/494-85中10#建筑沥青的标准,考察软化点、针入度和延伸度三项主要指标是否符合标准。通过实验室的研究证明:(1)可以单独用高凝减压渣油氧化生成合格的10#建筑沥青;(2)可以用低凝减压渣油参一定比例的催化油浆,生产出合格的10#建筑沥青;(3)高凝减压渣油参催化油浆液能够生产10#建筑沥青。

Abstract: The feedstock of 10#construction asphalt has been devel-oped from low pouring-point vacuum residue to high pouring-point vacuum residue and slurry. The 10#construction asphalt was developed by oxidation reaction using Dagang vacuum-residue of mixed high pouring-point oil, FCC slurry and low
pouring-point vacuum residue as the feedstock under experimen-tal conditions such as different proportion, air flow rate and oxi-dation temperature. On the basis of GB/494-85, whether the indexes of softening point, needle penetration and ductility ac-cord with the standard has been investigated. Results show that: (1) qualified 10#construction asphalt can be derived from
the oxidation of high pouring-point vacuum residue, (2) quali-fied 10#construction asphalt can be produced by low pouring-point vacuum residue mixing with a certain proportion of FCC slurry, (3) 10#construction asphalt can be produced by high pouring-point vacuum residue mixing with FCC slurry.

Key words: high pouring-point vacuum residue, low pour-ing-point vacuum residue, slurry, construction asphalt
