摘要

在微尺度化学反应器内对氢气/空气催化燃烧反应进行了研究，考察了操作条件对反应行为的影响，并建立相应的数学模型，同时也对该类反应器应用于强放热反应过程的动力学研究进行初步的探讨.实验过程中H2入口浓度为3% (mol)～15%（mol），结果表明微通道反应器可使处于爆炸极限内的氢氧催化燃烧反应在高空速、低压降、等温及动力学控制区内安全地进行.在H2入口浓度8%（mol）、反应温度150 ℃、空速1.0×106 h-1条件下，转化率高达90%.

Abstract

The catalytic combustion reaction of hydrogen/air mixture was studied in a microchannel reactor. The effects of operation conditions on reactor behavior were investigated in detail by using both mathematic modeling and experiment work. Explosive mixtures of hydrogen/air ［3%(mol)—15%(mol)］ were safely handled in this reactor. The results showed that catalytic combustion reaction can be operated at high space velocity

isothermal and kinetic controlled regimes. Under the conditions of inlet hydrogen concentration of 8%(mol)，reaction temperature of 150 ℃，space velocity of 106 h-1，hydrogen conversion was still higher than 90%.
