The comparison of plasma-catalytic pyrolysis behaviour with conventional catalytic pyrolysis was first investigated. The yield distribution before catalysis at various catalytic temperature are shown in Fig. 2a. Without plasma, direct pyrolysis of PP produced large amounts of liquid (62 wt%) with some gas (38 wt%) at 650 °C, while no solid product was produced. Upon increasing the catalytic temperature, the oil and gas yields decreased and increased to nearly 50 wt%, respectively. With plasma

Plasma-catalytic pyrolysis was developed for upgrading polypropylene (PP) pyrolysis volatiles to co-produce carbon nanotubes (CNTs) and hydrogen. To uncover the role of plasma on the plastic catalytic pyrolysis process, the pyrolysis of polypropylene (PP) over Fe/gamma-Al2O3 was carried out in a two-stage pyrolysis system with a coaxial dielectric barrier discharge (DBD) plasma reactor. The results showed that the plastic pyrolysis volatiles were further cleaved and activated with plasma, resulting in more active carbon species for the growth of CNTs. Compared to conventional catalytic pyrolys...
