In this work, the process intensification has been applied through simultaneous heat and mass transfer. A new multifunctional reactor for the co-production of hydrogen and aniline has been proposed. The heat required for the endothermic process (glycerol steam reforming) is provided by the exothermic process (hydrogenation of nitrobenzene to aniline). Additionally, all the required hydrogen for the aniline manufacture process is provided by a portion of the obtained hydrogen from the glycerol steam reforming via the membrane side. The achieved results of the glycerol steam reforming process have been compared with the conventional data. Acceptable improvement can be seen in the performance of the reformer, in which the conversion of glycerol and yield of hydrogen have improved by around 32% and 6.5%, respectively. Also, the conversion of the nitrobenzene displays an adequate number of 81.74%. Furthermore, a parametric analysis is accomplished to evaluate the performance of the reactors. Finally, the order of locations in the offered configuration has been reversed to investigate its effect on the simulation. The arrangement manipulation contributed to increasing the conversion of glycerol from 53.28% to 56.96 %, hydrogen yield from 4.83 to 4.89, and around 2.71% reduction of nitrobenzene conversion.

含甘油蒸汽重整和硝基苯加氢的新型多功能反应器的概念评价

在这项工作中,通过同时进行传热和传质来增强工艺。已经提出了一种用于氢气和苯胺联产的新型多功能反应器。吸热过程(甘油蒸汽重整)所需的热量由放热过程(硝基苯氢化成苯胺)提供。另外,苯胺生产过程所需的全部氢气是由甘油蒸汽重整所得的一部分氢气通过膜侧提供的。甘油蒸汽重整过程的成功结果已与常规数据进行了比较。在重整器的性能上可以看到可接受的改进,其中甘油的转化率和氢的产率分别提高了约32%和6.5%。还,硝基苯的转化率显示出足够的81.74%。此外,完成了参数分析以评估反应堆的性能。最后,颠倒了所提供配置中位置的顺序,以研究其对模拟的影响。布置操作有助于使甘油的转化率从53.28%增加到56.96%,氢产率从4.83增加到4.89,并且硝基苯转化率降低约2.71%。
