Title:
APPARATUS FOR RECYCLING PLASTIC MIXTURE CONTAINING POLYVINYL CHLORIDE, AND METHOD FOR RECYCLING PLASTIC MIXTURE CONTAINING POLYVINYL CHLORIDE BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/004560
Kind Code:
A1
Abstract:
Disclosed in the present specification are an apparatus for recycling a plastic mixture containing polyvinyl chloride, and a method for recycling a plastic mixture containing polyvinyl chloride by using the same. The apparatus, which is one aspect of the present invention, primarily performs pyrolysis through an auger reactor and a fluidized bed reactor and then, finally, performs filtering by means of a high-temperature filter filled with calcium oxide, and as a result, can prepare, from waste plastic, a pyrolysis oil, which has a low chlorine content, is free from wax and has a high aromatic compound content.
