本文通过数值方法对考虑丁烯ODH到丁二烯传质和传热的随机反应器和整体式固定床反应器模型进行了模拟和求解。通过基于两种反应器的多尺度模型分析转化率、温度分布和产物选择性，比较了整体式反应器和随机反应器在三种空隙率下的性能。还评估和讨论了催化剂孔隙率和催化剂热导率对整体式反应器的影响。整体式催化剂反应器比无规反应器表现出更好的反应和选择性；但在相同反应条件和接触时间下，其传热效率低于随机反应器。此外，在实际生产中还需要整体反应器控制的温度稳定性。
In this paper, both random reactor and monolithic fixed-bed reactor models that consider mass and heat transfer for the ODH of butene to butadiene were simulated and solved through a numerical method. The performances of the monolithic reactor and random reactors in three void fractions were compared by analysing the conversion rate, temperature distribution and product selectivity base on the multi-scale models of the two reactors. The influence of catalyst porosity and catalyst thermal conductivity on the monolithic reactor was also evaluated and discussed. The monolithic catalyst reactor showed better reaction and selectivity than the random reactors; however, its heat transfer efficiency was lower than that of the random reactors under the same reaction conditions and contact-time. Moreover, the temperature stability of the monolithic reactor control was needed in the actual production.
