Industrial gas purification is a cornerstone of modern chemical processing, ensuring product quality, process efficiency, and environmental compliance. Among the various contaminants that need removal, carbon monoxide (CO) is a common and often problematic one, particularly in streams destined for sensitive catalytic processes or high-purity applications. Understanding the science behind effective CO removal is crucial for selecting the right technologies. NINGBO INNO PHARMCHEM CO.,LTD. specializes in advanced catalytic solutions, and our expertise in metallic copper-based catalysts for CO removal is a key offering for the industry.

The efficacy of CO removal often hinges on the catalytic material's ability to selectively interact with and convert CO into less harmful or easily separable compounds. Metallic copper has emerged as a highly effective component in catalysts designed for this purpose. Its electronic structure and surface properties allow it to readily chemisorb CO molecules. When combined with suitable carriers, such as zinc oxide, and often enhanced with other promoters, these copper-based catalysts can facilitate reactions that transform CO into carbon dioxide (CO2) or other stable products, effectively reducing the CO concentration in gas streams. This makes them invaluable for hydrocarbon processing and other gas purification applications.

Our catalysts are engineered to operate within specific temperature windows, typically between 80°C and 220°C, with optimal performance often observed in the 150°C to 220°C range. This operating flexibility allows them to be integrated into existing industrial setups without requiring drastic modifications. The catalyst's ability to achieve very low CO concentrations, often below 0.1 ppm, is critical for processes where even minute traces of CO can deactivate downstream catalysts or compromise product quality. This is particularly relevant for propylene purification, where CO can poison polymerization catalysts.

The regeneration performance of these catalysts is another significant advantage. Over time, active sites on the catalyst surface can become deactivated due to the accumulation of byproducts or other adsorbed species. A regenerable catalyst can be treated to restore its activity, thereby extending its operational lifespan and reducing the frequency of replacement. This not only offers economic benefits but also contributes to a more sustainable industrial practice. For companies seeking to buy catalyst, the prospect of a long-lasting, regenerable solution is highly attractive.

Beyond propylene, these catalysts are employed in a variety of gas purification contexts. They are effective in removing CO from nitrogen streams, a critical application for industries requiring ultra-pure inert gases. The overall goal is to achieve trace CO removal from N2 and other gases, ensuring the integrity of sensitive chemical reactions and processes.
