摘要

通过解聚对聚氯乙烯（PVC）进行化学回收比聚烯烃更具挑战性，因为在热降解过程中会形成氯化氢。PVC脱氯化氢后的热降解产物为固体残渣，经800℃KOH处理，得到的高微孔碳材料最大BET表面积为3273 m2 g−1。一种钌催化剂负载在这种pvc衍生的碳上，对愈创木酚的加氢脱氧表现出很高的催化活性。本研究制备的高微孔碳载体是一种有价值的升级回收产品，可用于各种用途。

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

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 °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.
