Provided are an apparatus and a method for refining pyrolysis oil in which a dechlorination reaction is performed under a first hydrotreating catalyst. Hydrogen chloride as a by-product is removed, and then a denitrification reaction is performed under a second hydrotreating catalyst, thereby preventing production of an ammonium salt (NHCl), and providing refined oil. It is excellent in prevention of corrosion of a reactor, improvement of durability, occurrence of differential pressure, process efficiency, has very low contents of impurities such as chlorine, nitrogen, and metal and olefin, and has excellent quality.

Provided is a technology to convert an oil having a high content of Cl into a solvent. Impurities such as Cl, S, N, and metals are removed from an oil having a boiling point of 340&#xb0; C. or lower in a waste oil having a high content of Cl, and hydrogenation is carried out to recover an oil, and the oil may be applied as a solvent. Separation by boiling points to meet the properties of the solvent product is performed, a solid acid material and an oil having a high Cl content are mixed, impurities are removed by a heat treatment at a high temperature, and hydrogenation is carried out with a metal oxide catalyst, thereby manufacturing a solvent product.

Solvent composition prepared from waste oil and method of preparing the same

Provided is a method of producing naphtha from mixed plastic, the method including the following steps: (a) subjecting the mixed plastic to thermal pyrolysis; (b) separating a product produced in the thermal pyrolysis into first oil having a boiling point of lower than 150&#xb0; C. and second oil having a boiling point higher than that of the first oil; and (c) subjecting the second oil to catalytic pyrolysis.
