Hydrotreating Catalyst (WMNP) is a high-efficiency catalytic material engineered for selective hydroprocessing applications, ensuring effective removal of sulfur, nitrogen, and other impurities from petroleum feedstocks. Utilizing advanced metal-supported formulations, it enhances hydrogenation efficiency, optimizes fuel quality, and extends operational lifespan for industrial refining processes. This catalyst plays a vital role in fuel purification, petrochemical refining, and environmental compliance solutions, delivering consistent performance in controlled hydrotreating environments.
Product Overview
This hydrotreating catalyst uses a modified composite alumina as the support, with tungsten, molybdenum, nickel, and other metal components, along with additives. It is designed specifically for low-pressure hydrodesulfurization, hydrodenitrogenation, hydrodearomatization, and the removal of asphaltenes. The catalyst offers excellent catalytic activity, making it ideal for the hydrotreating of lower-grade gasoline and diesel in secondary processing. It features high compressive strength and abrasion resistance, is reusable, and shows excellent stability during long-term use, without causing corrosion to equipment. Compared to similar products in the domestic market, it has a 10-20% lower industrial packing density, which helps reduce catalyst loading costs significantly.
Key Features
- Excellent Hydrotreating Activity: Effectively removes sulfur, nitrogen, aromatics, and asphaltenes under low-pressure conditions, greatly improving the quality of petroleum products.
- High Compressive Strength and Wear Resistance: The catalyst has strong compressive strength and excellent wear resistance, offering a long service life and can be regenerated for reuse.
- Stable Activity: The catalyst maintains stable activity over time, making it suitable for long-term industrial use.
- Low Packing Density: Compared to similar products, this catalyst has a 10-20% lower packing density, helping to reduce the cost of catalyst loading.
Applications
- Secondary Processing of Low-Quality Gasoline and Diesel: Particularly suitable for hydrodesulfurization of crude oil products such as Shengli, Liaohe, Xinjiang, Zhongyuan, Guda, and Luning pipeline oils, as well as catalytic diesel from vacuum residue oil blending.
- Coking Diesel Hydroprocessing: Ideal for hydrotreating coking diesel, producing high-quality diesel with low sulfur and low aromatics.
- Industrial Units: The catalyst has been successfully applied in multiple industrial units, showing significant improvements, especially in medium and low-pressure hydrotreating processes.
