| Summary: | The mass transfer effect on the overall reaction rate in a cylindrical immobilized biocatalyst
has been investigated theoretically. Zero order and first order kinetics were taken into
consideration. The mass balance for the substrate on a cylindrical shaped biocatalyst results
into an ordinary differential equation (ODE) which can be solved numerically and/or
analytically using appropnate boundary conditions. Detailed steps for analytical solutions are
presented for zero and first order kinetics. The differential equation for zero and first order
kinetics was changed into a dimensionless form by defining suitable dimensionless variables.
The concentration profiles inside the porous biocatalyst were obtained as a function of Thiele
modulus. |
