Zhongtianli, a new favorite in the field of pseudo boehmite catalysts

Today, the editor of Zhongtianli will talk to you about the role of pseudo thin water aluminum in the field of catalysts. High purity pseudo boehmite, with a special microporous structure, is a high-end binder, carrier, and catalyst material in the catalyst industry, and an indispensable key material in the petroleum refining industry. China's high-end high-purity pseudo boehmite relies on imports, with Sinopec alone importing over 2000 tons annually.

High purity pseudo boehmite is a precursor for the production of high-purity alumina. Developed countries such as Europe and America have conducted extensive research on its preparation technology and application, and have entered the stage of large-scale production. Its technology is also far ahead of other countries and at a world leading level.

There are many enterprises in China that produce pseudo boehmite, and many scientific research institutes have conducted research on the preparation methods of different pseudo boehmite. Among them, the methods with industrial application value mainly include alcoholysis, ammonium aluminum sulfate thermal decomposition, and ammonium aluminum carbonate thermal decomposition. The high-purity alumina prepared by the alcohol salt hydrolysis method has high purity, but the cost is relatively high. The high-purity aluminum oxide obtained by the thermal decomposition method of ammonium aluminum sulfate is cost-effective and the operating process is simple and convenient, but the purity cannot meet the requirements, and the production of sulfur dioxide also pollutes the atmosphere. The thermal decomposition method of ammonium aluminum carbonate and the thermal decomposition method of ammonium aluminum sulfate do not produce much, and the performance difference of high-purity alumina produced is not significant. However, the thermal decomposition method of ammonium aluminum carbonate does not produce sulfur dioxide to pollute the atmosphere.

Due to the pursuit of low-cost and large-scale by most enterprises in China, most research work focuses on the production and research and development of low-end (purity less than 3N) pseudo boehmite and its subsequent products, leading to a serious dependence on imports for high-end SB powder in China. Although domestic units such as China Petroleum and Chemical Corporation's Institute of Stokes and Guizhou University have also conducted research on the preparation of high-purity pseudo boehmite, due to insufficient research work, domestic SB powder cannot enter the high-end market due to insufficient quality indicators such as purity, microstructure, and particle size, making it difficult to meet the demand of the high-end market.
