新型热管反应器在轻烃醚化中的研究及应用

将热管技术与催化反应器结合,构建了蛇形回路热管反应器。利用该反应器,进行了轻烃醚化工业侧线试验,考察了进料温度、液相体积空速、冷却水流量、进料浓度对反应结果的影响;测定了催化床层的轴向温度分布。利用反应器数学模型并结合试验数据,采用下山单纯形最优化方法获得了床层对热管的传热膜系数准数关联方程。所开发的新型热管反应器在2万t/a甲基叔丁基醚(MTBE)生产装置的扩能改造中应用成功。

Application and study on novel heat pipe chemical reactor in light iso-olefine etherisation process

With the combination of heat pipe technology and catalytic reactor,a novel-style ophidian loop heat pipe chemical reactor was established,by which an industrial sidetrack experiment with methyl tert-butyl ether(MTBE) synthesis was carried out.The factors which influenced the catalytic reaction results were investigated by changing feed temperature,liquid hour space velocity,cooling water flow rate,and feed concentration of reactants,the axial temperature distribution of the catalytic bed was studied at the same time.According to the experimental data and one-dimensional quasianalog-homogenous model of the reactor,the correlation equation of the heat transfer coefficient outside the ophidian loop heat pipes in the catalytic bed was obtained by means of numerical optimization method.The heat pipe chemical reactor was successfully used into the MTBE production plant with an annual capacity of 20 kt.
