研究開始時の研究の概要 |
Outline of research: Part 1: Preparation and characterization of BC-Ni/Fe catalysts Part 2: Pyrolysis-catalytic upgrading of e-waste plastics with BC-Ni/Fe catalysts Part 3: Regeneration and activation of BC-Ni/Fe catalysts Part 4: Life Cycle Assessment (LCA) of the overall process

研究実績の概要 |
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”.

今後の研究の推進方策 |
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.
