摘　　要：在气体均布的无机膜控制氧化反应器上进行了丁烯氧化脱氢制丁二烯反应，并将其与固定床方式反应的实验结果进行了对比，结果表明在实验范围内膜反应器比传统的固定床反应更为有效。建立了描述控制氧化膜反应器操作性能的数学模型，并将模型求解值与实验值对比，吻合良好。Controllable oxidative dehydrogenation of butene to butadiene was carried out in a novel inorganic membrane reactor(IMR) with oxygen uniform distribution. In this reactor butene and air (oxygen) were introduced into the two sides of the membrane separately. By means of adjusting the pressure difference across the membrane the permeation of air into the reaction region was controllable. The main reaction was promoted and the excessive oxidation of the hydrocarbons is eliminated. The experimental result showed that both the yield and selectivity of the butadiene obtained in the IMR were higher than those obtained in FBR obviously. The kinetic equations of oxidative dehydrogenation of butene over a ferrite catalyst were suggested and the mathematical model for simulating the operation characteristic of IMR was derived. The simulating results agree well with the experimental results. It appears that this kind of reactor can be used for other oxidation reactions.
