Introduction. As a fluid passes through a packed bed it experiences pressure loss due to factors such as friction. The relationships required to predict the pressure drop for a fluid flowing through a packed bed have been known for some time, with Darcy observing in 1896 that the laminar flow of water through a bed of sand was governed by the following relationship:

A packed-bed reactor is shown in Figure 13-2. When a reactor is packed with catalyst, the reacting fluid usually does not flow through the reac-tor uniformly. Rather, there may be sections in the packed bed that offer little resistance to flow, and as a result a major portion of the fluid may channel through this pathway. Consequently, the molecules following this pathway do not spend as ...

packed-bed and stirred-tank reactors. Scaleup of fluidized beds can be difficult (1). Fluidized beds are prone to erosion and particle attrition caused by the moving particles. Solids losses can result in significant operating costs, especially when the solid particles are an expensive catalyst. Bubbles also need to be managed, as large bubbles can travel faster than smaller bubbles in a ...
