The petroleum refining industry relies heavily on advanced catalytic technologies to transform crude oil into valuable fuels and petrochemical products. Among these, hydrotreating catalysts are indispensable for removing impurities like sulfur, nitrogen, and metals, and for saturating aromatic compounds. NINGBO INNO PHARMCHEM CO.,LTD. offers the WMNP-1 hydrotreating catalyst, a product that embodies innovation and efficiency in this critical sector. This article explores the key features and benefits of the WMNP-1 catalyst, highlighting its contribution to enhanced refining processes.

At its core, the WMNP-1 catalyst is built upon a foundation of promoted alumina, serving as an effective carrier for active metal components. The strategic inclusion of tungsten (WO3), molybdenum (MoO3), and nickel (NiO) results in a highly active catalyst capable of performing complex hydrotreating reactions. The concentration of these components, for instance, WO3 at 17-21 wt% and NiO at 3.5-5.5 wt%, are finely tuned to optimize catalytic performance. The physical form of the catalyst is trilope extrudates with a particle size of Ф1.6*5-15 mm, a shape that facilitates good contact with the feedstock while maintaining structural integrity within the reactor. The crushing strength, a critical indicator of mechanical robustness, is a minimum of 150 N/cm, ensuring it can withstand the process conditions without significant degradation.

The catalytic activity of WMNP-1 is further supported by its surface area (min 120 m2/g) and pore volume (min 0.25 ml/g). These characteristics are crucial for maximizing the accessibility of active sites to reactant molecules, thereby increasing the efficiency of the hydrotreating reactions. The packing density, ranging from 0.80 to 0.85 kg/l, also plays a role in reactor loading and operational efficiency.

The benefits of using the WMNP-1 catalyst are multifaceted. Its inherent good activity for HDS, HDN, aromatics saturation, and hydrodecolloidization in low-pressure environments directly translates into improved product quality and potentially higher yields of valuable distillates. This catalyst is particularly noted for its high resistance to compression and attrition, a critical factor in maintaining catalyst bed integrity and prolonging operational cycles between catalyst changes. Furthermore, its regenerable nature means that its performance can be restored, offering a sustainable and cost-effective solution for refiners. The absence of easily lapsed active components ensures that the catalyst does not cause corrosion to the refining equipment, safeguarding the plant's infrastructure and reducing maintenance costs.

The application of the WMNP-1 catalyst spans various refining streams. It is highly effective in the hydrotreating of poor secondary processed gas oil and diesel. Under medium and low operating pressure, it excels in treating all sorts of FCC diesel and coked diesel. The goal is to produce high-quality diesel oil with reduced aromatic content, a key market requirement. The reference operating conditions provided, such as for Daqing coked diesel, show that processed oil can achieve a dealkaline nitrogen rate of over 90%, underscoring the catalyst's efficacy. For refiners looking for reliable suppliers of hydrotreating catalyst, NINGBO INNO PHARMCHEM CO.,LTD. stands as a trusted partner.

In summary, the WMNP-1 hydrotreating catalyst from NINGBO INNO PHARMCHEM CO.,LTD. is a technologically advanced solution designed to meet the demanding requirements of modern petroleum refining. Its robust composition, excellent catalytic properties, and operational advantages make it a superior choice for enhancing efficiency, product quality, and cost-effectiveness in diesel production and other refining processes.
