Pseudo-boehmite has broad application prospects and the process technology of Chinese enterprises needs to be optimized

Pseudo-boehmite, also known as monohydrated alumina and pseudo-boehmite, is a kind of boehmite with incomplete crystallization. It is non-toxic, tasteless and odorless, and its appearance is white colloidal (wet product) or Powdered (dry product) is a new type of material with broad development prospects.

Pseudo-boehmite has the advantages of high specific surface area, large pore volume, strong adhesion, good peptization properties, strong corrosion resistance, good high temperature resistance, strong anti-pollution ability, and high crystal phase purity, and can be widely used in petroleum Chemical industry, automobile, rail transit, electronics, plastics, rubber, papermaking, construction, environmental protection and other fields.

Specifically, in the field of environmental protection, pseudo-boehmite can be used in tail gas treatment and wastewater purification scenarios; in the petrochemical industry, it can be used as a catalyst carrier for chemical reactions such as hydrocracking, isomerization, and alkylation. It can be used as an adsorbent for gas phase and liquid phase separation; in the fields of plastics and rubber, it can be used as a filler for coatings, plastics, etc. Among them, petrochemical industry is the main application field of pseudo-boehmite. In 2022, the demand for pseudo-boehmite in the global petrochemical market will exceed 250,000 tons.

There are various production methods for pseudo-boehmite, mainly including the carbonization method, which refers to the method of producing pseudo-boehmite by using the intermediate product NaAlO2 solution and CO2 as reaction raw materials based on the sintering method to prepare alumina; the alkali method is It refers to a method of adding a precipitant to an acidic aluminum salt solution and generating pseudo-boehmite through precipitation, filtration, washing and other processes; the acid method refers to using aluminum salts such as aluminum sulfate, aluminum nitrate, aluminum chloride as raw materials, and A method of neutralizing a soluble alkali to generate pseudo-boehmite; the aluminum alkoxide method refers to a method that uses high-purity aluminum hydroxide and saturated sodium hydroxide solution as raw materials and reacts under high temperature and high pressure conditions to generate pseudo-boehmite.

Globally, the companies planning to enter the boehmite market include German Sasol, German Nabaltec, Korean KCC Corporation, Korean Osang Group and other international companies, as well as Chiping Yutian Catalytic Materials, Henan Xinghao New Materials, Shanxi Xiaoyi Huaqing Aluminum, Xiaoyi Taixing Aluminum Magnesium, Chinalco Shandong New Materials, Xiaoyi Huazheng New Materials, Yueyang Huijing New Materials, Shandong Jinliwang Industrial and other Chinese companies.

According to the “2023-2028 Proposed Boehmite Industry Market In-depth Research and Investment Prospect Forecast Analysis Report” released by the Industrial Research Center It shows that Chinese companies mainly use the acid method and alkali method to produce pseudo-boehmite, with low product quality and poor environmental protection. In the future, companies need to continue to optimize the production process; foreign companies mainly use the aluminum alcohol method to produce pseudo-boehmite. Stone, the product has good quality and high purity, but the production cost is high.

Industry analysts said that overall, pseudo-boehmite is a type of material with broad development prospects. The new materials can be widely used in environmental protection, petrochemical industry, rubber, coatings and other fields. At present, many companies around the world have pseudo-boehmite production capabilities, but local companies have poor process technology and low technical levels. In the future, local companies will need to continue to optimize process technology and promote domestic pseudo-boehmite towards high purity and high performance. The direction continues to escalate.
