In July 2025, TUNA’s independently developed HC-LT50 ultra-low-temperature denitration catalyst achieved a NOx removal efficiency exceeding 90% at 150–170°C during online and sidestream tests at a leading Chinese steel plant. The results, verified by a third-party testing agency, confirmed the catalyst’s stable performance, with all metrics meeting or surpassing expectations, earning high praise from the steel plant’s management.
The months-long tests evaluated the catalyst’s performance under real industrial flue gas conditions, including both online operations and sidestream bypass testing. Data revealed that the HC-LT50 catalyst maintained consistent high efficiency (＞90% NOx removal) within the 150–170°C range, demonstrating strong resistance to sulfur and toxins, making it ideal for complex industrial flue gas treatment. Compared to conventional high-temperature denitration technologies, TUNA’s catalyst delivers high efficiency at significantly lower temperatures, reducing energy consumption. This breakthrough not only fills a gap in China’s ultra-low-temperature denitration market but also provides a practical solution for deep emissions reduction in steel, power, and chemical industries.
The steel plant’s management highly commended the catalyst’s exceptional stability and efficiency and expressed eagerness for further collaboration on environmental projects to advance green industrial development.
TUNA remains committed to innovating in environmental technologies and promoting low-carbon solutions. The company plans to expand the catalyst’s application to broader industrial scenarios while further optimizing its performance and adaptability, supporting China’s "Dual Carbon" goals.
