Beschreibung
Zusammenfassung:	The present invention relates to a method for continuously recovering a styrene monomer from waste polystyrene, and more specifically to a method for continuously recovering a styrene monomer from waste polystyrene, the method comprising mixing with a potassium carbonate (K2CO3) catalyst, and then continuously depolymerizing same, thereby enabling the recovery of a styrene monomer having high yield and high purity. La présente invention concerne un procédé de récupération en continu d'un monomère de styrène à partir de déchets de polystyrène, et plus particulièrement un procédé de récupération en continu d'un monomère de styrène à partir de déchets de polystyrène caractérisé en ce qu'il comprend le mélange avec un catalyseur de carbonate de potassium (K2CO3), puis la dépolymérisation en continu de celui-ci, ce qui permet la récupération d'un monomère de styrène ayant un rendement élevé et une grande pureté. 본 발명은 폐 폴리스티렌으로부터 스티렌 모노머의 연속 회수 방법에 관한 것으로, 보다 상세하게는 탄산칼륨(K2CO3) 촉매와 혼합 후 연속적으로 해중합시킴으로써 고수율 및 고순도의 스티렌 모노머를 회수할 수 있는 폐 폴리스티렌으로부터 스티렌 모노머의 연속 회수 방법에 관한 것이다.
