| Outline of Final Research Achievements |
Catalytic degradation of polystyrene/polypropylene mixtures has been carried out using gallium supported H-ZSM-5 zeolite catalyst. It has been found that the gallium catalyst is highly active for producing aromatic hydrocarbons in the degradation of the mixtures and the hydrogen atoms generated from the aromatization of polypropylene-decomposed fragments suppress the coking of polystyrene. The hydrogen transfer degradation thus developed is effective to establish a chemical recycling process in which waste hydrocarbon plastics are selectively converted into useful aromatic hydrocarbons. Furthermore, Zn/H-ZSM-5 also shows a high catalytic activity for the degradation of the plastics.
