Ammonia synthesis is a cornerstone of the global fertilizer industry and a critical process for many chemical manufacturers. At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the pivotal role that catalysts play in optimizing this complex process, particularly in the crucial step of carbon monoxide (CO) conversion via the water-gas shift reaction (WGSR).

The production of synthetic ammonia relies on a feedstock gas stream that is rich in hydrogen and nitrogen. However, raw synthesis gas often contains significant amounts of carbon monoxide and carbon dioxide, which are detrimental to the iron-based catalysts used in the final ammonia synthesis loop. Therefore, efficient removal of CO is essential. This is primarily achieved through the WGSR, where CO reacts with steam (H₂O) to produce hydrogen (H₂) and carbon dioxide (CO₂). To maximize hydrogen yield and minimize CO levels, advanced catalysts are employed.

Low Temperature CO Shift Catalysts (LTCS), often based on Cu-Zn-Al oxides, are particularly effective in this context. They operate at lower temperatures (180-260°C), which is advantageous for energy savings in ammonia plants. These catalysts are engineered for high activity, selectivity, and stability, ensuring that the CO content in the synthesis gas is reduced to very low levels (ppm range) before it enters the ammonia converter. The robust nature of these catalysts, including their mechanical strength and resistance to thermal degradation, ensures reliable performance over extended periods, a critical factor in the continuous operation of ammonia facilities.

NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality LTCS catalysts that are integral to efficient ammonia production. By utilizing these advanced chemical auxiliary catalysts, manufacturers can achieve higher synthesis gas purity, leading to improved ammonia yields and better catalyst performance in the downstream synthesis loop. Our commitment is to supply the chemical solutions that drive success and sustainability in the chemical industry.
