Abstract
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° 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.
