How to simulate a transient process of filling a natural gas tank with absorbents inside

I hope people who had experience with filling a tank with compressible gas would like to share their experience about how to set the boundary conditions and solver settings. Because it only has a inlet, no outlet, it makes simulation too difficult to converge at each time step.

I used Brinkman equation( br) for flow in the porous media, Heat Transfer in Porous Media （ht) for heat transfer with a source term which is the generated heat due to adsorption and an equation of kinetic of sorption. When I set inlet condition as a constant pressure, such as 3.5 MPa (I have used step function), its time steps were so small and stopped at a certain time step and never go further.

I really appreciate if anyone would like to give me some advice. Thanks ahead.
