Abstract
Provided is a technology of converting 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 180 to 340° C. in a waste oil having a high content of Cl, and hydroisomerization is carried out, thereby applying an oil having a high isoparaffin ratio as a solvent. After a separation by boiling points according to the properties of the solvent product, 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 hydroisomerization is carried out by a noble metal/1-D zeolite catalyst, thereby, manufacturing a solvent product.
