Shandong Bairu Chemical co.,ltd and Zibo Xiangrun Environment Engineering Co., ltd professionally produce activated alumina powder, activated alumina beads, activated alumina strip and other activated alumina. Activated alumina refers to intermediate alumina, which can be divided into three categories: high temperature alumina, low temperature alumina and ρ-A12O3. By selecting different kinds of raw materials, activated alumina with different specific surface areas can be prepared, and the pore size distribution of activated alumina can be changed by adding additives. The distinction of activated alumina can be distinguished by the method of x-ray analysis, and can also be distinguished by analyzing its raw material and its processing process. The industrial application of activated alumina can be divided into two categories: powder and beads, strip, cynlinder. The molding method is prepared by the rehydration characteristics of ρ-A12O3 or the hydrolysis behavior of pseudo-boehmite.The main application fields of activated alumina are adsorption field and catalyst field. In the field of adsorption, it can be used for gas drying, liquid drying, water purification, etc. In the field of catalysts, activated alumina can be used not only as a catalyst itself, but also as a catalyst carrier. With the deepening of people’s understanding of the structure of activated alumina, the application fields of activated alumina are also expanding.
The production of activated alumina:
- Prepared by ρ-
It mainly utilizes the rehydration characteristics of ρ-AO. The hydrated Bayerite can play a bonding role and become activated alumina during roasting.Using ρ- to produce activated alumina products can be made into various shapes, and even certain catalyst bodies can be directly formulated with activated alumina into powder to make activated alumina products with special shapes. Its application is being gradually promoted with people’s understanding of ρ-. - Prepared by pseudoboehmite. When the pseudo-boehmite is added with acid (such as H2SO4, HAC, etc.), a part of the particles can be hydrolyzed to become aluminum glue. After mixing with aluminum hydroxide powder, activated alumina products with different shapes and properties can be prepared.
