β¦ Synopsis
The paper presents a two dimensional model for a fixed bed catalytic reactor in which a distinction is made between fluid and solid temperatures and partial pressures. The importance of the boundary conditions for the radial heat transfer on predicted axial and radial profiles is illustrated. The present model is compared with previously published two dimensional models.

The performance of different two-dimensional models of fixed bed catalytic reactors is analyzed for different situations. The deviation of the response of the simplified models with respect to the heterogeneous one is explained in terms of the operative conditions and the value of dimensionless grou
A one-dimensional model, taking into account the diffusion of substrate between the liquid phase and the solid support, has been used to describe fixed bed enzyme reactors. The equations were solved numerically, and the values of the different parameters were calculated by a nonlinear regression met
