Zeolite membrane reactors

摘要: Abstract: Zeolite membranes, with their well-defined pore size, and high thermal chemical stability, can be used as membrane reactors. However, the development of zeolite reactors requires preparation defect-free membranes. Different methods for have been developed, including in situ secondary growth methods. The method has several advantages over method, such easier operation, higher controllability crystal orientation, a thicker microstructure level reproducibility. Despite enormous efforts made to improve quality these industrial application on large scale is confined T NaA zeolites use pervaporation vapour permeation processes. In addition, commercial zeolitic membranes cannot yet employed gas separation because presence inter-crystalline defects. This problem, along other disadvantages reproducibility problems step, cost modules sealing at temperatures, meant that there are relatively few papers processes interest. Therefore, further improvements necessary facilitate introduction into industry.
