High nitrogen resistant hydrocracking catalyst is a high-performance catalytic material designed for hydrocracking applications involving feedstocks with elevated nitrogen content. Engineered with advanced metal-supported formulations, it delivers superior nitrogen tolerance, optimized reaction kinetics, and enhanced hydrogenation efficiency, ensuring prolonged operational stability in industrial refining processes. This catalyst is widely used in petroleum refining, fuel upgrading, and hydrocarbon conversion, providing reliable performance for large-scale applications requiring resistance to nitrogen inhibition.
Product Overview
This hydrocracking catalyst features US-SSY zeolite and amorphous silica-alumina as the cracking components, with tungsten and nickel as the hydrogenation components. It is designed specifically for high-nitrogen hydrocracking processes, offering high activity and middle-oil selectivity. The key feature of this catalyst is its excellent nitrogen resistance, enabling it to maintain high activity and stability even when the nitrogen content of refined oils ranges from 20-50 ppm. Under more severe conditions, with nitrogen levels reaching 80-100 ppm, the catalyst continues to operate stably and is reusable. It has already been successfully applied in several hydrocracking units, demonstrating strong operational performance.
Key Features
- Excellent Nitrogen Resistance: Maintains high activity and stability under higher nitrogen conditions (20-100 ppm) in refined oils.
- High Activity and Middle-Oil Selectivity: Exhibits high catalytic activity and effectively promotes hydrocracking reactions with good selectivity for middle oils.
- Good Stability and Reusability: The catalyst can operate stably even under harsh conditions, and its performance can be restored through regeneration.
- Strong Adaptability: Suitable for various feedstock qualities, especially for high-nitrogen feedstocks in hydrocracking processes.
Applications
- High-Nitrogen Hydrocracking: Specially designed for the hydrocracking of high-nitrogen feedstocks, particularly effective for processing raw oils with high nitrogen content.
- Hydrocracking Units: Successfully applied in multiple hydrocracking units, showing excellent performance across a range of hydrocracking processes.
- Refining Processes: Suitable for use in hydrocracking during petroleum refining, helping to improve product lightening and increase yield.
