| Abstract: |
| The experimental study of waste tires pyrolysis in the vapor atmosphere was carried out in a tubular pyrolysis reactor.The results showed that，the waste tires started to decompose when the temperature was above 200 ℃，and the pyrolysis was intense when the temperature was in the range of 500 to 650 ℃.With the pyrolysis temperature increasing，the ratio and production rate of the gas increased，while the ratio of pyrolysis char kept stable.The pyrolysis char was a granular carbonaceous material with many pores in the interior.The mass fraction of carbon element was up to about 0.70 and the porosity was up to about 60%.The pores were mainly mesopores and few micropores were found.After further processing，the product has promising potential in applications such as macromolecules absorption. |
