Title:
フタル酸系ポリエステルおよび/またはポリ塩化ビニルを含む廃プラスチックから軽質油を製造する方法
Document Type and Number:
Japanese Patent JP3170290
Kind Code:
B2
Abstract:
Light-weight oil having a high octane number is produced from waste plastics containing phthalic polyester and/or polyvinyl chloride at a high yield without producing a phthalic sublimate or a carbonaceous residue. The light-weight oil is produced by pyrolyzing the waste plastics containing the phthalic polyester and/or the polyvinyl chloride in an atmosphere of steam or a mixture steam or an inert gas. A pyrolyzed oil and a pyrolyzed gas obtained by the phyrolysis of the above waste plastics may be catalytically cracked in an atmosphere of steam or a mixture of steam and the inert gas by using a catalyst. Further, it may be that after dechlorination is performed, the pyrolysis is carried out. Furthermore, it may be that the pyrolysis is performed in the presence of one or more kinds of iron hydroxide, hydrous iron oxide and iron oxide.
