AB - A two-component model of reactive liquid chromatography is presented  considering M!N type reaction. The model incorporates surface and pore  diffusions in the adsorbates, axial dispersion, interfacial mass transfer,  first order chemical reactions in the liquid and particle phases, and two  sets of boundary conditions. The model contains a system of four coupled  partial differential equations(PDEs) describing the dynamics of reactants  and products in both phases. The Laplace transformation and  eigen-decomposition technique are jointly applied to solve the model  equations analytically. An efficient and accurate numerical Laplace  inversion technique is utilized to retrieve back solutions in the original  time domain. The developed semi-analytical results are verified against the  numerical results of a high resolution finite volume scheme (HR-FVS). A good  agreement between the solutions not only confirms the accuracy of  semi-analytical results but also validates the accuracy of proposed  numerical scheme. This study extends and generalizes our previous analysis  on heterogeneous reactions in the liquid chromatography. In order to analyze  the behavior of a chromatographic reactor, different case studies are  presented showing the effects of model parameters on the process.
