Solvent Composition Prepared from Waste Oil and Method of Preparing the Same

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.

1 . A solvent composition prepared from a waste oil comprising:
 H-naphtha (˜C8, bp<150° C.) and Kero/LGO (C9-C20, pb 150-340° C.) at a weight ratio of 1:1 to 1:10, and   35 to 90 wt % of a paraffin, 0.1 to 30 wt % of a naphthene, and 0 to 10 wt % of an aromatic compound.   
     
     
         2 . The solvent composition prepared from a waste oil of  claim 1 , wherein
 the solvent composition includes 30 to 60 wt % of a normal paraffin, 5 to 40 wt % of an isoparaffin, 0.1 to 30 wt % of a naphthene, and 0 to 10 wt % of an aromatic compound.   
     
     
         3 . The solvent composition prepared from a waste oil of  claim 1 , wherein
 the solvent composition includes 60 to 80 wt % of the normal paraffin, 10 to 30 wt % of the isoparaffin, 1 to 15 wt % of the naphthene, and a balance of the aromatic compound, with respect to 100 wt % of a C6 component.   
     
     
         4 . The solvent composition prepared from a waste oil of  claim 1 , wherein
 the solvent composition includes 40 to 60 wt % of the normal paraffin, 5 to 25 wt % of the isoparaffin, 30 to 45 wt % of the naphthene, and a balance of the aromatic compound, with respect to 100 wt % of a C7 component.   
     
     
         5 . The solvent composition prepared from a waste oil of  claim 1 , wherein
 the solvent composition includes less than 3 wt % of an olefin and 0.5 wt % or less of a conjugated diolefin.   
     
     
         6 . The solvent composition prepared from a waste oil of  claim 1 , wherein
 the solvent composition includes less than 10 ppm of chlorine (Cl), less than 10 ppm of sulfur (S), and less than 10 ppm of nitrogen (N).
