| Abstract: |
| By analysing the effects of vacuum degree and particle bed thickness on the yield and composition of pyrolysis oil during pyrolysis process of waste tire in fixed-bed reacter with internals，the optimization of pyrolysis process of waste tire were investigated.The results showed that，increasing the pyrolysis vacuum and reducing the particle bed thickness could promote the pyrolysis oil and gas to flow out of the reactor faster，and avoid the secondary reaction of volatile matter as far as possible，so as to significantly improve the yield of pyrolysis oil.However，the proportion of gasoline fraction in the pyrolysis oil decreased，and that of distillate fraction increased.After optimization of pyrolysis process（vacuum degree was －5 kPa，particle bed thickness was 10 mm），the pyrolysis temperature had no obvious effect on the yield and composition of pyrolysis oil.When the pyrolysis temperature was 550～900 ℃，the yield of pyrolysis oil was kept at 50.1%～51.6%（Gejin analysis oil yield was above 95%），and the proportion of each component in pyrolysis oil had no obvious change. |
