废旧聚酯(PET)的化学循环利用

Chemical Recycling of Waste Poly(Ethylene Terephthalate)

废旧 PET聚酯可通过化学解聚来实现其循环利用。本文总结了废旧 PET聚酯化学循环利用领域的研究现状 ,介绍了目前国内外开发的主要化学解聚工艺方法 ,包括水解法、甲醇解聚法、乙二醇解聚法等 ,同时对各种工艺过程的优缺点进行了综合比较。

Waste poly (ethylene terephalate) (PET) can be recyclized by chemical depolymerization. This paper reviews the state of the art of chemical recycling of PET polyester and introduces several methods for chemical recycling such as hydrolysis, methanolysis, glycolysis and so on. At the same time, the advantages and disadvantages of each method on technical process are also compared.
