Packed Bed Adsorber - PDE

Hello,
I have an equation that I would like to solve. It is the basic equation which models adsorption on a packed bed adsorber:
0 = u*(dci/dz) + dci/dt + ([1-e]/e)*rho*(dqi/dt)
Where:
u - velocity
ci - concentration of component i in time t
z - length of the bed
t - time
e - voidage of the bed
rho - density of the component i
dqi/dt = adsorption energy which is the concentration of component i in the solid (adsorbent) that is given by the given equation:
dqi/dt = k*(q*-qi)
I have attached a paper which I want to simulate. How can I import this into matlab?

Use the method of lines.
Discretize the partial differential equation
0 = u*(dci/dz) + dci/dt + ([1-e]/e)*rho*k*(q-qi)
in space.
Now solve the resulting system of ordinary differential equations (consisting of the discretized PDE and the ODE for the adsorbat concentration) using ODE15S, e.g..
Best wishes
Torsten.
