摘　　要：以正丁烷的液相异构化反应为例,探究了移热速率对稳态非等温理想连续搅拌釜式反应器(CSTR)和活塞流反应器(PFR)效率的影响。研究结果表明:从反应器绝热操作到具有一定换热速率,再到冷却介质温度不变的情况,随换热速率增大,达到一定转化率时所需的CSTR和PFR反应体积曲线由一个交点、到两个交点,再到相切,最终无交点,即随换热速率增大,在不同阶段两种理想反应器效率的相对大小不同。此结果可为理想反应器的选型提供指导。The liquid-phase isomerization reaction of normal butane was taken as an example. The effects of heat exchange rate on the efficiency of steady state non-isothermal ideal continuous stirred tank reactor （CSTR） and plug flow reactor （PFR） with exothermic reaction were analyzed. The results demonstrated that the reactor operated under adiabatic condition, certain heat exchange rate with surroundings, and the constant temperature of cooling medium with the maximum heat transfer rate, i.e. with the increasing of heat exchange rate, the conversion curves of key component in CSTR and PFR with specific reaction volume at first existed an intersection point, then two intersection points, and then a tangent point, finally no intersection point. It meant that with the increasing of heat exchange rate, the relative magnitude of the efficiency of two types of ideal reactor was different at different stages. The analysis results could provide guidance for the selection of the ideal reactor.
