A study has been made on the consecutive adsorption of CO/H2 gases on Pt/SiOz catalysts at 523 K using breakthrough measurements.
The criteria for dispersion, diffusion and change in the pore size is evaluated and discussed as well as the equilibrium kinetic curves, which
show to what extent the rates of sorption of one of the gases is affected by the presence of the other. The changes in average pore radii, surface
areas and pore volume were very well estimated and correlated well with the breakthrough data.
