摘　　要：基于铜基载氧体,运用流程模拟软件Aspen plus对化学链空分制氧系统展开了研究,构建化学链制氧系统模型,分析了反应温度,载气流量等因素对系统性能的影响,对化学链空分制氧系统进行参数优化。此外,本文也构建了传统的深冷空分制氧系统,与化学链制氧系统进行了对比分析。结果表明:较高的释氧反应器温度可提高氧气浓度和氧气的摩尔流量;水蒸气流量的增加也有利于释氧反应的进行。与深冷空分制氧技术相比,化学链空分制氧技术不仅系统能耗较低,而且制备的氧气浓度也较高。The process simulation software Aspen Plus was used to study the chemical looping air separation oxygen production system based on copper based oxygen carriers.A model of the chemical looping air separation for oxygen production system was constructed,and the effects of reaction temperature,carrier gas flow rate on system performance were analyzed.The parameters of the chemical looping air separation oxygen production system were optimized.In addition,a traditional cryogenic air separation for oxygen production system was also constructed and it was compared with a chemical looping air separation for oxygen production system.The results showed that a higher temperature of the oxygen release reactor could increase oxygen concentration and molar flow rate of oxygen at the outlet of the oxygen release reactor.The increase in water vapor flow rate was also beneficial for the oxygen release reaction.Compared with cryogenic air separation technology,chemical looping air separation technology not only had lower system energy consumption,but also produced higher oxygen concentration.
