The surfaces of its micropores possess the properties required for catalysis, such as adsorption capacity, surface activity, and excellent thermal stability; therefore, it is widely used as a catalyst and catalyst carrier in chemical reactions. Activated alumina is produced by dehydrating aluminum hydroxide at a low temperature of 140°C. It is not only a raw material for producing synthetic corundum, synthetic rubies, and sapphires, but it is also used in the production of substrates for modern large-scale integrated circuits. Activated alumina has a wide range of applications; its industrial form is typically colorless or slightly pink cylindrical particles with good compressive strength. It is a commonly used adsorbent, catalyst, and catalyst carrier in petroleum refining and petrochemical industries ； In industry, it is used as an acid scavenger for transformer oil and turbine oil, and it is also employed in chromatographic analysis ； In the laboratory, it is a medium-strength desiccant whose drying capacity is comparable to that of phosphorus pentoxide; after use, it can be regenerated and reused by being heated at temperatures below 175°C for 6–8 hours, which gives it great value in the field of environmental protection. Active alumina is an alumina with adsorption properties and catalytic activity, characterized by porosity, high dispersion, and a large specific surface area. It is a solid material with high porosity and good dispersion, possessing a large specific surface area. It has excellent adsorption properties as well as good resistance to pressure, wear, and heat; therefore, it is widely used as an efficient adsorbent, desiccant, and catalyst carrier for various reactions. At the same time, it is also the preferred material for environmental protection. Activated alumina is a commonly used chemical with numerous applications, including adsorption, water purification, catalysis, and drying. It is thus widely utilized as a desiccant, catalyst, water purifier, etc. Moreover, different methods are employed for its production depending on the intended use. When using activated alumina, attention should also be paid to relevant precautions. Do not open the package before use to avoid moisture absorption, which may affect its performance. The product is suitable for deep drying, and it is advisable to use it under conditions where the pressure is greater than 5 kilograms per square centimeter. After being used for a certain period of time, the adsorption capacity of the product will gradually decline; it should be regenerated to remove the absorbed water so that it can be reused for gas treatment processes. This product is non-toxic; it must be kept dry and protected from moisture, and contact with oil or oil vapors is strictly prohibited.
