NUMERICAL SOLUTION OF A TWO-DIMENSIONAL MODEL FOR NON-ISOTHERMAL CHROMATOGRAPHIC REACTOR PACKED WITH CORE-SHELL PARTICLES
The use of core-shell particles in a fixed bed column of reactive liquid chromatography is simulated to analyze the effects of core-shell particles application under nonisothermal conditions. The developed model equations form a nonlinear system of convection-diffusion-reaction partial differential equations coupled with algebraic equations for isotherms and reactions. A semi-discrete high resolution finite volume scheme is implemented to approximate the solutions of the system of partial differential equations. A few consistency checks
are carried out to verify the model accuracy and numerical scheme. The obtained results are helpful for further improvements of non-isothermal chromatographic reactors which consider axial as well as radial concentration and thermal gradients.
