PRODUCTION OF HIGH-BOILING SOLVENT WITH HIGH AROMATIC CONTENT

PURPOSE:To obtain the subject solvent having a low mixed aniline point at a low production cost by partially recycling a reforming reaction product of a kerosene fraction and simultaneously distilling, separating and recovering a specific fraction from the resultant produced oil. CONSTITUTION:A kero...

Zusammenfassung:	PURPOSE:To obtain the subject solvent having a low mixed aniline point at a low production cost by partially recycling a reforming reaction product of a kerosene fraction and simultaneously distilling, separating and recovering a specific fraction from the resultant produced oil. CONSTITUTION:A kerosene fraction or a raffinate obtained after recovering n-paraffins therefrom is subjected to reforming reaction. A fraction having the boiling point within the range of 205-245 deg.C is then distilled and separated without distilling and separating the resulting formed oil. Part of the distilled and separated fraction as a reforming raw material is recycled and a fraction having the boiling point within the range of 205-245 deg.C is recovered to afford the objective solvent having
