In order to control the interaction between the filling and the analyte at short times (flow through conditions) and thus, its effect on the analytical signal and the presence of interferences, the initial adsorption velocities were calculated using the pseudo second order model.
In the process of methane molecules adsorption, the maximum velocity of the K@C601+ motion is 515.5 m/s (t = 32 ps).
To improve the efficiency of offshore natural gas exploitation, CO2 separation from offshore natural gas in quiescent and flowing states using 13X zeolite was studied systematically by examining the voidage, adsorption time, inlet velocity, adsorber diameter, temperature, and pressure.

The carrier gas flow rate can be varied from 40 up to 4000 N cm3 min−1 allowing measurement of dynamic adsorption coefficient with face velocities from 0.3 up to 923 cm min−1 depending on the gas pressure and the test cell being used.
We also consider wall effects caused by two factors: increased velocity and decreased adsorption capacity.
The effect of inlet air humidity and velocity on the adsorption process for each bed layer was studied at different inlet velocities and at different air humidities.
The solution allows for general radial- and time-dependent inlet/outlet conditions, complex boundary conditions on the duct wall including adsorption and decay, and arbitrary velocity profiles of the transporting fluid.
