摘　　要：采用钙钛矿型致密透氧膜对甲烷部分氧化制合成气进行了膜反应实验研究，并建立了该膜反应的数学模型。模拟计算结果与实验结果吻合较好：通过该模型考察了绝热条件下的反应床层温度分布，以及恒温反应体系中温度、流量、反应器长度等因素对膜反应结果的影响。The partial oxidation of methane to syngas(CO+H2) was studied in a perovskite-type dense O2- semipermeable membrane reactor for inveshgating the new route of natural gas conversion, and a theoretical model was developed to simulate the tube-and-shell configuration membrane reactor. The experimental results suggested that over 95% CH4 conversion and 98% Co selechvity were obtained using the reactor at 1158K, He:CH4 20:1, air flow rate 100ml·min-1 and tube side now rate 60ml·min-1. Good agreement was obtained between the experimental results and model calculation. The simulation results suggested that adiabatic membrane reaction was very mild, compared with adiabatic fixed-bed reaction Which could cause temperature runaway. The effects of reaction temperature, inlet flow-rate and membrane reactor length was investigated on reaction results. It suggested that suitable operation parameters were necessary for good reaction results and lower cost of equipment and operations.
