WMCN hydrogenation refining catalyst is a high-performance catalytic material designed for efficient hydrogenation and refining applications in petrochemical and fuel processing industries. Engineered with advanced metal-supported formulations, it ensures optimized reaction kinetics, superior impurity removal, and extended operational lifespan, making it a critical component for large-scale hydrocarbon purification processes. This catalyst enhances fuel quality, reduces sulfur content, and supports environmentally sustainable refining solutions.
Product Overview:
The WMCN hydrogenation refining catalyst is a high-efficiency catalyst designed for hydrogenation refining. It uses modified composite alumina as the support, loaded with metal components such as molybdenum, tungsten, cobalt, and nickel, and includes additives to enhance performance. The catalyst exhibits excellent low-pressure hydrogenation desulfurization, denitrification, de-aromatization, and de-asphaltene capabilities. With strong compressive and wear resistance, it maintains stable activity and can be regenerated for reuse. This catalyst avoids the loss of active components that could cause equipment corrosion, making it ideal for the hydrogenation refining of low-quality gasoline and diesel. It produces ultra-low sulfur, low-aromatic high-quality diesel.
Key Features:
- Excellent Low-Pressure Hydrogenation Activity:Suitable for hydrogenation refining under medium to low pressure conditions, effectively removing harmful impurities.
- High Compressive and Wear Resistance:Offers a long service life in industrial applications, reducing the need for frequent replacements.
- Low Catalyst Filling Cost:Due to its low bulk density, it significantly reduces the cost of catalyst filling.
- Stable Activity:The catalyst demonstrates excellent activity and stability over extended periods of use.
Applications:
- Low-Quality Diesel Hydrogenation Refining:Widely used in secondary refining of diesel in regions such as Shengli, Liaohe, and Xinjiang, improving diesel quality.
- High-Sulfur Diesel Desulfurization:Effectively processes high-sulfur diesel, reducing sulfur content to below 300ppm.
- Petroleum Refining:Suitable for various types of feedstock oils, including pipeline oil and coking oil, producing ultra-low sulfur, low-aromatic high-quality diesel.
- Coking Diesel Hydrogenation Refining:In the hydrogenation refining of coking diesel, it effectively removes impurities to meet environmental and quality standards.
