Studies on Phenomenological Parameters of Fixed - Bed Reactors

In its simplest form a fixed- bed reactor consists of a cylindrical tube packed with pellets
of catalysts. Reactants passed through the bed of catalysts and converted into products in an
amounts depending upon the numerical values of certain parameters. While some of the quantities
making up these parameters are well defined physically, certain others are not. Parameters of the
latter group largely characterize the macroscopic heat and mass transfer processes which occur
within fixed bed and the reactor wall or a coolant outside the wall. In this paper a detailed discussion of these macroscopic quantities is taken up.
