Understanding
of the interaction between cellulose and various
plastics is crucial for designing waste-to-energy processes. In this
work, co-pyrolysis of polystyrene (PS) and cellulose was performed
in a Py-GC×GC/MS system at 450–600 °C with ratios
70:30, 50:50, and 30:70. Polypropylene (PP), polyethylene (PE), and
polyethylene terephthalate (PET) were then added to the mixture with
different ratios. It was found that co-pyrolysis of PS and cellulose
promotes the formation of aromatic products with a large increase
in the yield of ethylbenzene as compared to the calculated value from
individual feedstock. This indicates interactions between cellulose
and PS pyrolysis products. Observations from experiments including
more than one type of plastics indicate that the interactions between
different plastics are more pronounced than the interaction between
plastics and cellulose.
