<P>PROBLEM TO BE SOLVED: To provide a method of removing at least 90% of an aromatic olefin without losing an aromatic hydrocarbon to supply as general purpose aromatic solvent raw material, an aromatic hydrocarbon oil consisting of an aromatic hydrocarbon having 100-250°C of a boiling point as a principal ingredient produced at a petroleum refining industry, a petrochemical industry or a coal chemistry industry, and containing an aromatic olefin. <P>SOLUTION: A purification method of an aromatic hydrocarbon oil includes: a step in which an aromatic hydrocarbon oil consisting of an aromatic hydrocarbon of a boiling point of 100-250°C as a principal ingredient, and containing an aromatic olefin of a boiling point of 100-250°C is added with an acid catalyst, and subjected to polymerization step; and a distillation step in which the aromatic hydrocarbon oil performed with the polymerization step is distilled to recover an aromatic hydrocarbon of a boiling point of 100-250°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
