Compared with imported products, excellent performance and low price The two new catalysts developed by Zhejiang Deqing Sanlong Catalyst Co., Ltd. will make the currently widely used Claus sulfur recovery device end the long history of foreign monopoly of catalysts. The reporter learned from Sanlong Catalyst Co., Ltd. on January 14 that the two sulfur recovery catalysts developed by the company have been tested by authoritative departments. The catalytic performance exceeds the level of imported products, but the price is much lower than that of imported products. The successful development of these two kinds of catalysts will not only improve China's coal, oil, and natural gas processing levels, but will also push China's environmental protection work to a new level.
According to Shen Binglong, chairman of Sanlong Company, sulfur-containing crude oil will produce pollutants such as acidic gases and sulfur-containing flue gas during processing, which will not only pollute the environment, but also cause huge waste. British scientists first invented the Claus sulfur recovery process as early as 1883. Later, German scientists made major improvements to it, making the Claus sulfur recovery process device an internationally accepted device. At present, the catalyst used in this device in China has long been monopolized by foreign countries. According to statistics, in 2006 China had a total of 138 sets of Claus sulfur recovery units, which required an annual catalyst of 250 million yuan. All of these catalysts were imported from abroad.
The original Claus sulfur recovery unit used a bauxite catalyst and later developed into an alumina catalyst. However, due to the limitation of the operating conditions, the alumina catalyst may cause a decrease in reactivity due to sulfation poisoning; in addition, trace amounts of oxygen may also degrade the catalytic activity. In view of this, titanium dioxide catalysts have become the current development direction of international sulfur recovery catalysts. Researchers also proposed adding a set of tail gas hydrogenation device before the emission of sulfur-containing tail gas, and hydrogenation of the sulfide in the tail gas to hydrogen sulfide through a titanium dioxide hydrogenation catalyst before returning to the Claus sulfur recovery device. After the tail gas was burned, it was vented to make it "zero".
According to Shen Binglong, the most important characteristic of titanium-based Claus sulfur recovery catalyst developed by Sanlong Catalysts Company is high reactivity, which almost reaches the thermodynamic equilibrium conversion rate; followed by the strong hydrolysis ability of organic sulfur, the hydrolysis rate is almost aluminum trioxide More than double the catalyst. The catalyst also has strong resistance to poisoning. Once the catalyst is "poisoned" due to abnormal operating conditions, it can quickly reach its original activity level after normal operating conditions are restored. In addition, the company has also specially developed tail gas hydrogenation catalysts with higher low-temperature activity, and the performance is significantly better than that of imported similar products. The organic sulfur hydrolysis activity is more than 98%, and it is an excellent hydrogenation catalyst.
