Abstract Activated alumina is a porous material with good thermal stability, moderate surface area, adjustable pore volume and pore size, good adsorption performance and surface acidity. It is widely used as a catalyst carrier. The liquid phase method is currently the most widely used method for synthesizing activated alumina powder in laboratory research and industrial application. The powder prepared by the method has the advantages of narrow particle size distribution and regular morphology. In this paper, the main liquid phase methods such as aluminum alkoxide hydrolysis and neutralization are reviewed.

| About author:: Chunxia Che, Senior Engineer of Lanzhou Center of Petrochina Petrochemical Research Institute, was selected as the 2019 Hou Debang Chemical Science and Technology Youth Award. She has been engaged in research and development of hydrogenation catalysts since 2006, presided and participated in over 15 projects of Petrochina, and won 7 provincial and ministerial awards, 5 prefecture-level awards, and 73 authorized invention patents. More than 30 papers published in core journals at home and abroad. As the person in charge of the pre-hydrogenation of acetylene in Petrochina,, after more than ten years of painstaking research, PEC-21, a pre-hydrogenation catalyst independently developed by Petrochina, has undergone small-scale development and pilot research, and finally achieved industrial application and promotion, and won the first prize of the technical invention of China National Petroleum Corporation. |
