摘要: Oxygen is industrially produced by cryogenic distillation but the process energy-intensive. Perovskite membranes can provide an economical solution for oxygen production because of low energy input. However, technology not commercialized due to one challenges which sealing membrane at high temperature. Unfortunately, there no universal sealant that be used all perovskite membranes. Factors such as material, geometry and operating conditions critically affect selection. This paper overviews current methods long-term separation with various geometries disk, tubular hollow fiber.
