一种化学链连续制氧方法
摘要：
本发明公开一种化学链连续制氧方法，属于化学制备领域；将空气作为反应原料气从载氧膜的一侧通入，同时将载气从载氧膜的另一侧通入，其中载氧膜的厚度为1～3mm，每mm2载氧膜通过空气的流量为0.08～0.76Ncm3?min-1，每mm2载氧膜通过载气的流量为0.12～0.82Ncm3?min-1，同时在反应压力为1～2atm，温度为800～1000℃下反应0.5～200小时，在通入载气的载氧膜一侧进行收集，即得纯氧气；本发明的在一个反应器内完成，可连续生产，比传统的化学链制氧的产量高，成本低。
摘要（英）：

The invention discloses a chemical looping continuous oxygen generation method, belonging to the field of chemical preparation. The method comprises the following steps: introducing air as a reaction raw material from one side of an oxygen carrying membrane and simultaneously introducing carrier gas from the other side of the oxygen carrying membrane, wherein the thickness of the oxygen carrying membrane is 1-3mm, the flow of the oxygen carrying membrane which passes through the air per mm<2> is 0.08-0.76Ncm<3>.min<-1>, and the flow of the oxygen carrying membrane which passes through the carrier gas per mm<2> is 0.12-0.82Ncm<3>.min<-1>; reacting under the pressure of 1-2atm at the temperature of 800-1000 DEG C for 0.5-200 hours, and collecting on one side, from which the carrier gas is introduced, of the oxygen carrying membrane to obtain pure oxygen. According to the method, the oxygen generation operation is finished in a reactor and oxygen can be continuously produced; compared with a conventional chemical looping oxygen generation method, the method has the characteristics that the yield is high and the cost is low.
