Abstract

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.

热处理聚氯乙烯（PVC）衍生的高微孔碳载体：在加氢处理催化中的应用

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。
