Thermally treated polyvinyl chloride (PVC)-derived highly microporous carbon support: applications in hydrotreating catalysis

초록

Chemical recycling of polyvinyl chloride (PVC) via depolymerization is more challenging than that of polyolefins because hydrogen chloride forms during thermal degradation. The thermal degradation of PVC yields a solid residue after dehydrochlorination, which, upon KOH treatment at 800 degrees C, produces a highly microporous carbon material with a maximum BET surface area of 3273 m2 g-1. A ruthenium catalyst supported on this PVC-derived carbon exhibits high catalytic activity for the hydrodeoxygenation of guaiacol. The highly microporous carbon support prepared in this study serves as a valuable upcycled product for various applications.
