PROBLEM TO BE SOLVED: To provide a method for producing a naphthenic hydrocarbon solvent having a slight malodor and a low content of aromatics and excellent in solubility of resins, etc., without exhibiting toxicity to human bodies, and a normal chain paraffin. SOLUTION: This method for producing a low-aromatic hydrocarbon solvent and a normal chain paraffin comprises (1) a step of hydrodesulfurizing a kerosene fraction, (2) a step of distilling off a gas and a light fraction and obtaining a kerosene fraction with a low sulfur content, (3) a step of separating and recovering the normal paraffin from the kerosene fraction with a molecular sieve comprising a synthetic zeolite and providing a residual oil and (4) a step of nuclearly hydrogenating the residual oil and providing the solvent with <=1 mass % of aromatic content. |
