| 以中海SZ36 1减三线馏分油为原料,经糠醛抽提方法制备富芳再生剂调和组分,并与中海AH 90沥青调和制备符合SH/T 0819 2010标准的5种再生剂产品,考察5种再生剂对老化沥青的再生性能。结果表明:SZ36 1减三线馏分油经糠醛抽提得到的高芳抽出油符合SH/T 0819 2010规定的RA5再生剂的各项指标要求,可以作为再生剂开发的优质原料;SZ36 1抽出油与AH 90沥青按不同比例复配可以制备出黏度等级分别为RA25、RA75、RA250和RA500的再生剂;含有沥青组分的再生剂制备的再生沥青,其短期抗老化性能和长期抗老化性能均优于参比沥青,不仅满足产品的技术要求,还表现出良好的应用性能。 |

| Abstract: |
| CNOOC SZ36 1 vacuum distillate cut was refined by furfural extraction method and the high aromatics recycling agent ingredients were obtained. Five kinds of recycling agents that meet the requirements of RA25 to RA500 in SH/T 0819 2010 standard were prepared. The recycling performances of the recycling agents were studied. The results indicate that the extracted oil with high aromatics content, which was prepared from SZ36 1 vacuum distillate cut via furfural extraction, meets the RA5 recycling agent of SH/T 0819 2010 standard. And it can be utilized as the good raw material of recycling agent. The recycling agents of RA25, RA75, RA250 and RA500 can be produced through different formulations between SZ36 1 extracted oil and AH 90 asphalt. The recycled asphalts obtained by recycling agents containing a certain amount of virgin asphalt have better anti aging property than that of extraction of SZ36 1 distillate as well as the reference asphalt AH 70. The recycling agents obtained meet the specification of products and show good application performance. |
