Description

Technical field

[0001] The invention relates to a method for upgrading mineral spirits, selecting suitable catalysts, and producing low-sulfur, low-aromatic, high-quality mineral spirits with fractions with a boiling range of 140-350°C. Background technique

[0002] Solvent oil is a light petroleum product that dissolves, dilutes, washes and extracts certain substances. Its boiling point is in the range of gasoline and kerosene fractions. The key control indicators for its quality are sulfur and aromatics content. At present, domestic solvent oil brands mainly include No. 6 extract solvent oil, aviation washing gasoline, fragrant flower solvent oil, petroleum ether, rubber solvent oil, washing solvent oil, paint solvent oil and aluminum foil rolling oil. Among them, aluminum foil rolling oil is mainly used in the processing of aluminum foil containers for food and beverages. To ensure people's health, aluminum foil rolling oil requires sulfur content <2.0μg / g and aromatics <...
