| 研究実績の概要 |
We have prepared the different catalysts for catalytic pyrolysis of plastics. The co-pyrolysis of printed circuit board (PCB) and waste tire was conducted and the results have been summarized. 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 submitted to the international journal for review.
We attended the Pyro Asia Symposium 2020 on 11-13, December 2020, and gave a presentation. We rewarded the “YOUNG RESEARCH AWARD” at this symposium, furthermore we gave another invited lecture entitled “Migration of bromine during the pyrolysis of printed circuit boards”.

理由
Firstly, we prepared the biochar by the fast pyrolysis of cedar wood. The Fe/biochar catalyst was synthesis using the impregnation method. Meanwhile, the one-pot synthesis of Fe/biochar was conducted by using the pre-impregnation of Fe ion into biomass and pyrolysis at 600 °C for 4h. Furthermore, the ZSM-5 and hierarchical ZSM-5, Fe loading hierarchical ZSM-5 was prepared by acid/alkali treatment for comparison.
The co-pyrolysis of PCB and waste tire was conducted and the results has been summarized into a paper.

| 今後の研究の推進方策 |
We are conducting the fast pyrolysis and the catalytic pyrolysis of printed circuit board 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. The reactivity of regenerated catalysts for the pyrolysis-catalytic upgrading process will be evaluated.
