Qinghai Yuntianhua signs contract with Sichuan Shutai for SCST series catalysts Author/Source: Gasification World Date: 2021-12-30 Clicks: 10 Recently, through an open tender conducted by Yunnan Tendering Co., Ltd., Qinghai Yuntianhua International Fertilizer Company of Yuntianhua Group decided to use the SCST-231 type low-temperature shift catalyst and the SCST-241-5Q type methanation catalyst produced by Sichuan Shutai Chemical. Yuntianhua Group Co., Ltd. is a state-owned comprehensive industrial group that focuses on the production of fertilizers and products for modern agriculture, as well as glass fiber materials. It also engages in various other business areas such as petrochemicals, phosphate mining and processing, phosphorus chemicals, trade and manufacturing services, and industrial finance. Qinghai Yuntianhua International Fertilizer Company is the wholly-owned subsidiary of Yuntianhua Group that offers the widest range of fertilizer products. Covering an area of over 1,300 mu, it has a synthetic ammonia production facility with an annual capacity of 400,000 tons, urea or high-efficiency compound fertilizer production facilities with an annual capacity of 800,000 tons, diammonium phosphate production facility with an annual capacity of 240,000 tons, and a compound fertilizer production facility with an annual capacity of 200,000 tons. The total annual production capacity is 1.24 million tons. The SCST-231 series of copper-based CO low-conversion catalysts utilize high-performance catalysts produced through Shutai’s patented technology. They not only retain the advantages of traditional low-conversion catalysts but also incorporate new insights and theories from recent research in catalyst science, granting them unique performance advantages over similar catalysts available both domestically and internationally. This catalyst is produced using a novel supported co-precipitation process, which improves upon traditional ammonia-complexation and reverse-addition production methods. It features low loss on ignition, minimal shrinkage, good dispersion of active components, excellent anti-poisoning properties, high strength, strong erosion resistance, and minimal by-products. The SCST-241-5Q methanation catalyst is a new type of titanium-rare earth-nickel catalyst suitable for use in ammonia synthesis or other hydrogen production facilities. It is capable of removing low-concentration amounts of carbon monoxide and carbon dioxide from hydrogen-rich feed gases, converting them into the inert gas methane and water, which can be easily removed. This catalyst boasts unique properties: high strength, high pore volume, high activity, and ease of installation and removal. It performs significantly better than other catalysts under high pressure and high flow rates. To date, it has been used in nearly 200 installations in China, and it is also exported to regions such as Southeast Asia, Belarus, and the Middle East. The SCST-231 series of copper-based CO low-conversion catalysts have been successfully used in the 450,000 tons/year ammonia synthesis plants of CNOOC Hainan Fudao Phase II (built by KBR), the 540,000 tons/year plant in Ordos Chemical Industry (the largest in China), the 300,000+300,000 tons/year plants in Ordos United Chemical, the 300,000 tons/year plant in Xinjiang Tianyun, and the 450,000+300,000 tons/year ammonia synthesis plants in Chongqing Jianfeng. Since these large-scale nitrogen fertilizer manufacturers began using this type of catalyst, the stability of plant operation, their service life, and energy consumption have all reached record levels. Its overall performance is significantly better than that of the catalysts previously used by multinational companies, resulting in good economic benefits. It has thus become a representative example of high-quality domestic catalysts, reinforcing its leadership in terms of performance and efficiency.
