A Classification of Reactor Models

Points (1) and (2) require further explanation, and for this we must distinguish between gradients at the local or particle level, as considered in Chapter 8, and gradients at the 

Derive the continuity and energy equations for an FBCR model based on pseudohomogeneous, two-dimensional, DPF considerations. State any assumptions made, and include the boundary conditions for the equations. 

Continuity equation from a material balance for A around the control volume, 

The most useful form of the continuity equation (or material balance) is that which enables calculation of the amount of catalyst (W) required in terms of /a (at the bed depth x). Since
