| Abstract: |
| Taking the naphthenic vacuum third-line distillate SZ36-1 as the raw material，the single
stage high pressure hydrogenation experiments were carried out with the self-made hydrofining ZQC catalyst
and the imported catalyst，respectively. Under the condition of reaction pressure of 15 MPa and hydrogenoil
volume ratio of 1 000/1，the preparation of environmental friendly aromatic rubber plasticizer A0709
（A0709 for short） at different space velocity and reaction temperature was studied. The results showed that，
A0709 products that met the requirements of GB/T 33322—2016 could be produced with self-made ZQC
catalyst when the space velocity was 0. 5 h-1 and the reaction temperature was not less than 320 ℃. The reaction
temperature was about 20 ℃ lower than the reaction temperature when the imported catalyst was used. The
filling performance of A0709 for insoluble sulfur was comparable to that of commercial rubber oil |
