Mineral oil is a common organic solvent widely used in industrial production and daily life. However, during production or processing, mineral oil often contains some color and impurities that affect its quality and appearance. To improve the quality and purity of mineral oil, it is often necessary to decolorize and purify it. Activated carbon is a common decolorizing and purifying material, offering high efficiency, simplicity, and environmental benefits.

Introduction to Activated Carbon Decolorization
Activated carbon has a highly developed porous structure and a large specific surface area, enabling it to effectively adsorb impurities and color molecules from liquids or gases. In the decolorization process, activated carbon physically adsorbs color molecules from mineral oil onto its surface, achieving a decolorizing effect.
Methods of Activated Carbon Decolorization
Static Decolorization
Static decolorization involves placing the mineral oil in a bed of activated carbon, allowing the color molecules to be adsorbed onto the activated carbon’s surface.
Dynamic Decolorization
Dynamic decolorization involves passing the mineral oil through a bed of activated carbon, utilizing the adsorption properties of the activated carbon to remove color molecules from the oil.
Activated Carbon Purification
Activated carbon not only decolorizes but also effectively removes impurities from mineral oil. These impurities include solid particles, liquid colloids, and organic contaminants that affect the quality and purity of mineral oil. The adsorption capability of activated carbon allows these impurities to be captured on its surface, achieving a purifying effect.
Methods of Activated Carbon Purification
The methods of purification are similar to those of decolorization, including static and dynamic purification.
Static Purification
Static purification involves placing the mineral oil in a bed of activated carbon, allowing impurities to be adsorbed onto the activated carbon’s surface.
Dynamic Purification
Dynamic purification involves passing the mineral oil through a bed of activated carbon, utilizing its adsorption properties to remove impurities.
Effects of Activated Carbon Decolorization and Purification
Activated carbon decolorization and purification significantly improve the quality and purity of mineral oil. After treatment, the mineral oil becomes more transparent, with lower impurity content, meeting higher industrial standards.
Precautions for Activated Carbon Decolorization and Purification
Selecting the Right Type of Activated Carbon
Different types of activated carbon have varying adsorption properties and applications. Choose the appropriate type based on the characteristics of the mineral oil and the processing requirements. In our experience, wood activated carbon is widely used in mineral oil purification process. Wood activated carbon with developed macropores, which can effectively adsorb pigments and impurity macromolecules.
Controlling the Amount of Activated Carbon
The amount of activated carbon should be determined based on the volume and concentration of the mineral oil. Overuse or underuse of activated carbon can lead to suboptimal treatment results.
Controlling Treatment Time
The treatment time for activated carbon decolorization and purification should be determined based on actual conditions. Too short or too long treatment times can lead to unsatisfactory results.
Timely Replacement of Activated Carbon
The adsorption capacity of activated carbon is limited. When the activated carbon reaches a certain saturation level, it needs to be replaced or regenerated to maintain treatment effectiveness.
Conclusion
Activated carbon decolorization and purification are effective methods for treating mineral oil, enhancing its quality and purity. During the treatment process, it is essential to select the appropriate type and amount of activated carbon, control treatment time and temperature, and replace or regenerate the activated carbon in a timely manner to ensure effective and safe processing.
