Problems solved by technology

Although the method has the characteristics of simple equipment and low operating costs, it also has the disadvantages of non-hydrogen solvent oil production technology; CN 1157847A has introduced a method for producing solvent oil in the presence of nickel catalyst and hydrogen, which has the advantage of having liquid The yield is high, there are no environmental problems such as three wastes, and the disadvantage is that the odor of the product cannot be completely removed, indicating that the hydrogenation depth of this technology is not enough; CN 1258720A introduces a production method for solvent oil using conventional hydrogenation refining technology, and its disadvantage is that only It can remove impurities such as sulfides, nitrides, oxides, organic acids, phenols, olefins, and aromatics in the fraction, and cannot open the ring of some naphthenes, and cannot cause moderate hydrocracking reactions in the heavy fractions in the feed. To achieve the purpose of reducing the viscosity and density of the distillate

Embodiment 3

[0035] According to the operating conditions of Example 2, the post-refined catalyst bed uses the same catalyst as the upgraded catalyst, and other conditions are the same. The reaction results are shown in Table 7. It can be seen from the data in the table that the post-refined catalyst bed has a great effect on improving the bromine index of the product.

Abstract

The invention relates to a method of hydrogenation to improve quality of solvent oil. The invention takes one or more petroleum fractions from petrol, coal oil, diesel oil as raw materials, contactly reacting with hydrogenation catalysis containing ª

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 <...
