At NINGBO INNO PHARMCHEM CO.,LTD., we are constantly exploring novel materials and processes to address critical environmental challenges. Our latest breakthrough lies in the development of advanced catalysts for Selective Catalytic Reduction (SCR) of Nitrogen Oxides (NOx), derived from an unexpected source: modified rare earth tailings. This initiative not only tackles the pressing issue of industrial air pollution but also champions the principles of the circular economy by repurposing mining byproducts.

The vast quantities of rare earth tailings, often considered waste, are rich in valuable mineral components, including iron and cerium, which possess inherent catalytic properties. Our research team has meticulously developed a process involving alkali and acid co-treatment to significantly enhance these properties. This modification process revitalizes the tailings, transforming them into a potent catalyst capable of efficient NOx removal, particularly at high operational temperatures.

Our modified rare earth tailings-based catalyst has demonstrated remarkable performance, achieving up to 96.2% NOx conversion at 900°C. This superior efficiency is a direct result of the enhanced structural properties observed through advanced characterization techniques. We've noted an increase in surface porosity, the appearance of surface cracks, and a higher prevalence of active Fe and Ce species. Furthermore, analyses confirm an improved redox capacity and a broadened reduction temperature range, crucial for effective catalytic activity.

The advantages of this innovation are manifold. Firstly, it presents a significantly more cost-effective solution compared to conventional SCR catalysts, making advanced emission control accessible to a wider range of industries. Secondly, it directly addresses the environmental concerns associated with mining waste accumulation. By transforming tailings into a functional material, we are contributing to a cleaner environment and a more sustainable industrial future. The high SCR NOx reduction efficiency achieved by this catalyst is a testament to its robust design and the synergistic interplay of its components.

NINGBO INNO PHARMCHEM CO.,LTD. is proud to pioneer this technology, offering industries a powerful tool for managing NOx emissions. This development underscores our commitment to innovation, sustainability, and providing practical solutions for a cleaner world. We believe that by intelligently utilizing existing resources, we can achieve both environmental protection and economic benefits, paving the way for more responsible industrial practices.
