| Outline of Annual Research Achievements |
We have prepared the different catalysts for catalytic pyrolysis of plastics. The experiments have been done by the tandem micro-reactor GC/MS. The co-pyrolysis of PCB and waste tire was conducted. We find that the co-pyrolysis of PCB and waste tire can be beneficial for the production of phenol and largely reduce the content of brominated compounds. The related work has been published in the journal of Green Chemistry and Journal of Hazardous Materials.
We attended the International Symposium on Feedstock Recycling of Polymeric Materials, and gave a presentation on the topic of “Co-pyrolysis of the non-metallic fraction of printed circuit boards and waste tire”.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The ZSM-5 and hierarchical ZSM-5 prepared by acid/alkali treatment and Fe loading biochar was prepared. The catalytic co-pyrolysis of PCB and waste tire has is being conducted.
|
| Strategy for Future Research Activity |
We are conducting the fast pyrolysis and the catalytic pyrolysis of PCB and waste tire. The main goals on the product quality and yield, and the migration behaviors of contaminants will be evaluated. The catalytic mechanisms on the degradation of plastics and the removal of contaminant will be comprehensively studied.
The regeneration and activation of catalysts will be conducted under different conditions. Different regeneration methods will be performed to optimize the regeneration conditions.
Attend the 23rd edition of the International Conference on Analytical and Applied Pyrolysis, 15-20 May, 2022.
