✦ Synopsis

Trickle-bed catalytic reactors find applications in situations where it is necessary or expedient to contact a gas and a liquid phase in a fixed-bed reactor. Such reactors are usually operated in the cocurrent mode to allow high flowrates of liquid and gas, which would cause flooding in countercurrent situations. Of course, cocurrent operation implies that the gas-liquid transfer resistance is not rate-limiting. The boundary between the gas and liquid phases is not fixed, but fluctuates in a highly complex manner as the fluids interact in finding their way through the Dacked bed.
