METHOD FOR CONVERTING POLYVINYL-CHLORIDE-CONTAINING PLASTIC INTO OIL AND DEVICE FOR CONVERTING POLYVINYL-CHLORIDE-CONTAINING PLASTIC INTO OIL

WIPO Patent Application WO/2023/112937

A1

Provided are a method for converting polyvinyl-chloride-containing plastic into oil and a device for converting polyvinyl-chloride-containing plastic into oil that make it possible to obtain hydrocarbon oil at a high yield from polyvinyl chloride. The method for converting a plastic that includes polyvinyl chloride into an oil has a hydroxylation step S3 for hydroxylating polyvinyl chloride to form a hydroxide and a thermal decomposition step S4 for converting the hydroxide into hydrocarbon oil gas through thermal decomposition, the method making it possible to obtain hydrocarbon oil from polyvinyl chloride. The device for converting a plastic that includes polyvinyl chloride into an oil has a hydroxylation unit for hydroxylating polyvinyl chloride to form a hydroxide and a thermal decomposition unit for converting the hydroxide into hydrocarbon oil gas through thermal decomposition, the device making it possible to obtain hydrocarbon oil from polyvinyl chloride.
