Development of Pseudo-Boehmite
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. Promote the development of high-purity pseudo-boehmite industry.
Pseudo-boehmite, also known as pseudo-boehmite, alumina monohydrate, is an alumina hydrate with a special spatial network structure, formed during the synthesis of aluminum hydroxide, with large pore volume, large specific surface area, etc. physical properties. Pseudo-boehmite has a wide range of applications, and has been used in many fields such as petroleum, automobile, fire protection, papermaking, construction, environmental protection, etc. Among them, it is used as a binder in the petrochemical field for catalysis and cracking catalysts. In terms of demand, the demand reaches 42,000 tons/year.
According to the research and analysis report, 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 industrial industry, the performance of pseudo-boehmite products has been continuously optimized and gradually developed towards the direction of high-purity pseudo-boehmite. High-purity pseudo-boehmite has a special microporous structure, is a high-end binder, carrier and catalytic material, and is an indispensable material in the field of petroleum smelting. At present, my country's high-purity pseudo-boehmite market demand still relies on imports, and the annual import volume of Sinopec alone reaches 20,000 tons, and there is a large room 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. 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 laid out research in this field. At present, large-scale production has been achieved, and it is in a leading position in the global market.
There are many domestic enterprises that can produce pseudo-boehmite. At present, the industrialized production processes mainly include alkoxide hydrolysis, ammonium aluminum carbonate thermal decomposition, and aluminum ammonium sulfate thermal decomposition. Among them, the high-purity oxidation produced by alkoxide hydrolysis The purity of aluminum is high, but the production cost is high; the thermal decomposition method of aluminum ammonium sulfate has a simple production process and low cost, but the product purity is low, and the environmental pollution is relatively large; the thermal decomposition method of aluminum ammonium carbonate and the thermal decomposition of aluminum ammonium sulfate The production process of the method is similar, but it does not produce sulfur dioxide in the production, and the environmental protection is high.
