On July 16, a reporter learned from the ammonia synthesis catalyst technology exchange and new product promotion conference held in Dalian that a groundbreaking ferrous-based ammonia synthesis catalyst, jointly developed by Zhejiang University of Technology and Liaoning Panjin Southern Chemical Liaohe Catalyst Co., Ltd., has achieved a major breakthrough. This new catalyst breaks away from the traditional ferrous sulfate system that has been used internationally for over 80 years, marking a significant milestone with full independent intellectual property rights. Its successful application in 39 companies across the globe highlights its substantial potential in driving energy efficiency and reducing emissions in the ammonia industry.
According to data provided by ammonia production companies using this technology, the Amomax-10H pre-reduction catalyst can save 5 tons of turbine steam per hour when used in 130 tons of capacity. It also reduces the reduction time by 3 to 4 days. This results in cost savings of about 5 million yuan, eliminates ammonia discharge during the entire reduction period, and increases ammonia production by over 100 tons, adding approximately 9 million yuan in production value. When combined with the Amomax-10H oxidation catalyst, using 200 tons of the products can boost daily ammonia output by 11.9%, leading to an annual increase of 39,000 tons of synthetic ammonia and 63,000 tons of urea.
The new ferrous-based ammonia synthesis catalyst has already been successfully industrialized and is now being used in 11 countries, including Germany, the U.S., Russia, and Japan, as well as large-scale facilities in China. By 2006, there were 30 users, and the number has since grown to 39. Industry experts predict that by 2010, more than 80% of China’s large-scale ammonia plants will adopt this advanced catalyst.
It is worth noting that most of China’s synthetic ammonia producers are small or medium-sized enterprises, which often operate at a smaller scale, with high energy consumption and costs. Some facilities consume nearly double the energy of global best practices. In 2005, the sector consumed around 79 million tons of standard coal, accounting for 25.9% of the total energy use in the petroleum and chemical industry. As a major energy consumer in China’s chemical sector, the adoption of this new catalyst could significantly improve both energy efficiency and environmental performance across the industry.
Tan Zhuzhou, honorary president of the China Petroleum and Chemical Industry Association, praised the new catalyst highly. He emphasized that the government and industry are actively supporting energy-saving and emission-reduction efforts in the ammonia sector, encouraging the adoption of new, energy-efficient, and environmentally friendly equipment, processes, and technologies to boost production while lowering energy consumption.
