Abstract
With the acceleration of the industrialization process, the importance of gas purification technology in environmental protection and industrial production has become increasingly prominent. Porous ceramic membranes show great potential in gas purification because of their excellent thermal stability, chemical stability and designability. In the introduction, this paper first introduces the background and significance of the research, and emphasizes the key role of porous ceramic membrane in gas purification technology. In the part of structural characteristics of porous ceramic membrane, the relationship between microstructure, porosity and gas separation performance and the effect of surface properties on gas adsorption are analyzed in detail. These structural characteristics play a decisive role in the separation efficiency and selectivity of ceramic membranes. In the part of preparation technology, the traditional preparation method and advanced preparation technology are discussed, including extrusion forming method, sol-gel method, 3D printing technology and so on. At the same time, the regulation of membrane pore structure and the selection and synthesis of membrane materials are discussed. These factors have important effects on the properties of ceramic membranes. In the part of physicochemical properties, the pore structure, mechanical properties, thermal and chemical stability and surface properties of porous ceramic films are systematically studied. These characteristics determine the reliability and durability of ceramic membranes in practical applications. In the part of performance optimization strategy, this paper puts forward some optimization measures such as membrane material modification strategy, optimal pore structure design, heat treatment and surface coating technology. These strategies are designed to improve the separation efficiency of ceramic membranes, enhance their mechanical strength and improve their durability. In conclusion, this paper systematically studies the performance of porous ceramic membrane in gas purification technology, and provides a scientific basis for the design and preparation of high performance porous ceramic membrane. With the advancement of material science and preparation technology, the application prospect of porous ceramic membranes in the field of gas purification will be broader, and it is expected to provide more efficient and reliable solutions for environmental protection and industrial production.
