Fluid phase mass balance:
(∂C_i)/∂t+u.(∂C_i)/∂z+ρ_p ((1-ε_b)/ε_b ) (∂q_i)/∂t-D_L (∂^2 C_i)/(∂z^2 )=0 1.
Fluid phase initial and boundary conditions:
Initial conditions; C_i (z,0)=q_i (z,0)=0 2.
Boundary conditions: Assume Danckwert’s BCs for a dispersed plug flow;
at bed inlet (Z=0)
εD_L (∂C_i)/∂z │_(z^+ )=-u(C_i │_(z^- )-C_i │_(z^+ ) ) 3.
at bed outlet (Z=L)
(∂C_i)/∂z │_(z^- )=0 4.
Sorbent mass balance:
(∂q_i)/∂z=k_i*(q_i^*-q_i ) 6.
Equations 1 through 6 can be solved using COMSOL Multiphysics to obtain the adsorption breakthrough curve.

I have a similar problem as yours? maybe we can communicate some ideas about it?
