| Outline of Final Research Achievements |
The catalytic degradation of polyolefin/polystyrene mixtures using gallium-supported H-ZSM-5 catalyst was investigated to develop a new technology for chemical recycling of waste plastics. When the concentration of polystyrene in plastic mixtures was about 20%, great coking suppression of polystyrene on the catalyst surface by polyolefin-derived hydrogen was observed and the conversion of the plastics into aromatics proceeded efficiently. Furthermore, from the results of the model reactions using 1-octene and styrene monomer, it was found that the hydrogenation and hydrocracking of styrene monomer were accelerated, while the coking following the dimerization of styrene monomer was suppressed in the presence of polyolefin-derived hydrogen.
