熟悉滴流床反应器（TBR）的稳态行为和优点，在过去的二十年里，研究人员和工艺工程师不断探索周期性（或循环）操作滴流床反应器的非稳态流体动力学，以从其效率和性能中提取更多。尽管其复杂的非线性行为，归因于在工业规模的过程控制安全，TBR的循环操作是一个有前途的过程强化技术，具有巨大的潜力，在工业TBR的实施。本文总结和回顾了近年来TBR循环运行的研究进展及其各种运行方式的潜在应用。与其流体力学放大和设计的几个问题进行了讨论，重点是在流量调制过程中产生的冲击波衰减。
Familiarized with the steady state behavior and advantages of the trickle bed reactors (TBR), for the past two decades, researchers and process engineers are continuously exploring the unsteady state hydrodynamics of periodically (or cyclic) operated trickle bed reactors to extract even more from its efficiency and performance. Despite its complicated nonlinear behavior that attributes to the process control safety at the commercial scale, cyclic operation of TBR is a promising process intensification technology that has immense potential for implementation on industrial TBR. In this paper, we have summarized and reviewed the research and progresses made in recent years on cyclic operation of TBR and potential applications of various mode of its operation. Several issues associated with its hydrodynamics scale-up and designs have been discussed with an emphasis on shock wave attenuation that arises during flow modulation.
