Hydrotreating supplementary refining catalyst for lubricating oil is a high-performance catalytic material designed to enhance the purification and upgrading of lubricating oil feedstocks. Engineered with advanced metal-supported formulations, it ensures superior hydrogenation efficiency, effective impurity removal, and improved viscosity stability. This catalyst is widely used in lubricant refining, petrochemical processing, and industrial hydroprocessing applications, delivering reliable performance in controlled refining environments to meet stringent quality standards.
Product Overview
This hydrotreating supplementary refining catalyst for lubricating oil uses alumina as a support and contains tungsten and nickel active components. It is specifically designed for the hydrotreating process of lubricating oil. The catalyst offers excellent hydrogenation activity, effectively removing colorants and unstable components from lubricating oil, thereby improving its appearance and performance. Its unique characteristics, such as low pour point recovery and low bed pressure drop, ensure efficient and stable hydrotreating processes. Additionally, the catalyst has high compressive strength and abrasion resistance, making it easy to handle and suitable for long-term use.
Key Features
- High Activity: The catalyst exhibits good hydrogenation activity, efficiently removing undesirable components from lubricating oil to improve its quality.
- Good Decolorization Performance: Significantly improves the color of lubricating oil, making it clearer and more transparent.
- Low Pour Point Recovery: Ensures the stability of the lubricating oil’s performance during the hydrotreating process, avoiding issues related to pour point recovery that may affect product quality at low temperatures.
- Low Bed Pressure Drop: The catalyst features a small bed pressure drop, enhancing reaction efficiency and reducing energy consumption.
- High Compressive Strength and Wear Resistance: With strong compressive strength and wear resistance, the catalyst is suited for high-load industrial operations, extending its service life.
Applications
- Lubricating Oil Hydrotreating: Primarily used for the supplementary hydrotreating and refining of lubricating oils, improving color, stability, and lubricating performance.
- Petroleum Product Refining: Suitable for other petroleum products that require decolorization and refining during processing, improving product appearance and quality.
