The drive for cleaner air necessitates advanced technologies for exhaust gas treatment. Selective Catalytic Reduction (SCR) remains a cornerstone of NOx emission control, and the performance of the SCR catalyst is central to its success. At NINGBO INNO PHARMCHEM CO.,LTD., we are at the forefront of SCR catalyst manufacturing, leveraging innovative techniques like mechanochemical synthesis to produce high-performance alumina-based catalysts. This article delves into the manufacturing process and highlights the advantages our catalysts offer to industrial clients.

Our manufacturing process begins with carefully selected raw materials, focusing on high-purity alumina as the primary support. The key to achieving superior catalytic performance lies in the precise incorporation of active elements such as vanadium and lanthanum. Unlike conventional wet impregnation methods, our mechanochemical synthesis approach involves milling the precursor materials together. This solid-state reaction method offers several advantages: it reduces solvent usage, potentially eliminates complex post-synthesis purification steps, and can lead to materials with unique structural and chemical properties. For example, this method has allowed us to create mesoporous alumina structures with excellent surface area, which are critical for accommodating a high density of active catalytic sites.

The optimization of this synthesis route is paramount. We meticulously control parameters such as ball milling time, the concentration of vanadium precursors (like NH4VO3), and lanthanum precursors (like LaCl3·7H2O). Our research indicates that an optimal grinding time of around 3 hours, combined with specific vanadium loadings, yields the most beneficial material properties. Furthermore, the introduction of lanthanum can significantly influence the surface charge characteristics of the catalyst, which plays a role in the adsorption of gaseous reactants. As a leading manufacturer, we understand that consistent quality is vital for our customers looking to buy industrial chemicals.

Performance metrics such as NOx conversion efficiency, resistance to poisoning (especially from sulfur dioxide, SO2), thermal stability, and operational lifetime are key considerations in our manufacturing. Our alumina-vanadia-lanthana catalysts have demonstrated excellent SCR performance, with impressive NOx reduction rates. The mechanochemical method ensures a homogenous distribution of active species throughout the alumina matrix, contributing to uniform catalytic activity and preventing localized deactivation. We take pride in being a reliable manufacturer and supplier, offering competitive pricing and readily available samples for evaluation.
