Isothermal Design of Heterogeneous Packed Catalytic Reactors

ISOTHERMAL DESIGN OF HETEROGENEOUS PACKED CATALYTIC REACTORS 

A quantitative strategy is discussed herein to design isothermal packed catalytic tubular reactors. The dimensionless mass transfer equation with unsteady-state convection, diffusion, and multiple chemical reactions represents the fundamental starting point to accomplish this task. Previous analysis of mass transfer rate processes indicates that the dimensionless molar density of component i in the mixture I must satisfy (i.e., see equation 10-11)  

In a packed catalytic tubular reactor, reactants are converted to products via chemical reaction on the internal surface of the catalyst. This problem was described in detail for a single isolated pellet. At this stage of the design, one seeks an expression for the volume-averaged rate of reactant consumption within
