my country’s high-purity pseudo-boehmite market demand relies on imports, and the industry still has development opportunities

Pseudo-boehmite, also known as pseudo-boehmite and monohydrated alumina, is an alumina water compound with a special spatial network structure. It is formed during the synthesis of aluminum hydroxide and has large pore volume and large specific surface area. physical properties. Pseudo-boehmite has a wide range of applications and is used in many fields such as petroleum, automobiles, fire protection, papermaking, construction, and environmental protection. Among them, it is used as a binder in catalysis and cracking catalysts in the petrochemical field. The demand reaches 42,000 tons/year.

According to the“2022-2027 Proposed Boehmite Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that pseudo-boehmite has high application demand in the chemical industry, but the product requirements are not high. With the high-end development of the modern chemical industry, the performance of pseudo-boehmite products has been continuously optimized and gradually developed towards high-purity pseudo-boehmite. High-purity pseudo-boehmite has a special microporous structure and is a high-end binder, carrier and catalytic material. It is an indispensable material in the field of petroleum refining. At present, my country’s high-purity pseudo-boehmite market demand still relies on imports. The annual import volume of Sinopec alone reaches 2,000 tons, and there is a large space for domestic substitution in the future.

High-purity pseudo-boehmite is the precursor for the production of high-purity alumina. During the “14th Five-Year Plan” period, with the development of high-tech industries such as domestic aviation and military industry, rail transit, etc., the application demand for high-purity alumina continues to rise, and thus Promote the development of high-purity pseudo-boehmite industry. The production of high-purity pseudo-boehmite has a great impact on the development of high-tech industries. Therefore, developed countries such as Europe and the United States have already deployed research in this field. They have now achieved large-scale production and are in a leading position in the global market.

There are many domestic companies that can produce pseudo-boehmite. The currently industrialized production processes mainly include alkoxide hydrolysis, aluminum ammonium carbonate thermal decomposition, and aluminum ammonium sulfate thermal decomposition. Among them, high-purity oxidation produced by alkoxide hydrolysis is The purity of aluminum is higher, but the production cost is higher; the thermal decomposition of aluminum ammonium sulfate method has a simple production process and lower cost, but the product purity is lower and it causes greater environmental pollution; the thermal decomposition of aluminum ammonium carbonate and the thermal decomposition of aluminum ammonium sulfate The production process of the method is relatively similar, but it does not produce sulfur dioxide during production and is more environmentally friendly.

There are many companies in the field of pseudo-boehmite in my country, but most of them pursue low cost and large scale, and the products they produce are mostly concentrated in the low-end field. The purity of the products is lower than 3N, resulting in domestic dependence on high-purity pseudo-boehmite. import. At present, domestic Sinopec Research Institute, Guizhou University and other units are conducting research on high-purity pseudo-boehmite. However, the current technology is immature and the product quality is poor, making it difficult to meet high-end market demand.

Industrial analysts said that pseudo-boehmite, as an important material produced by smelting and high-purity alumina, benefits from terminal With the development of the industry, the market demand is higher and it is gradually developing in the direction of high purity. At present, my country has realized the production of pseudo-boehmite, but high-purity pseudo-boehmite products rely on imports. The current production technology is backward, the quality of the products produced is poor, and it cannot meet the needs of high-end fields. There is huge room for development of the high-end market in the future.
