Description
technical field
[0001] The invention belongs to equipment for directly separating and preparing pure oxygen from air and a preparation method thereof, in particular to the preparation of an oxygen ion-electron mixed conduction ceramic hollow fiber membrane reactor. technical background
[0002] Oxygen production by air separation is of great significance in environmental protection and industrial production. For example, in thermal power plants, pure oxygen is used to replace air, and pure carbon dioxide that can be recycled will be obtained in the combustion process instead of being discharged into the atmosphere as a greenhouse gas. . Oxygen is often used as an oxidant in chemical production. If air can be used directly as a raw material, the production cost will be greatly reduced.
[0003] At present, oxygen production from air separation is mainly realized through processes such as cryogenic distillation or pressure swing adsorption, and the cost is high. Although org...
