C<strong>on</strong>clusi<strong>on</strong><br />

The results of both static and dynamic sorpti<strong>on</strong> measurements in the studied bimodal<br />

micropore carb<strong>on</strong> system can be correlated. Changes in the ratio of two parallel micropore<br />

diffusi<strong>on</strong> processes with different time c<strong>on</strong>stants distinguished in the FR rate spectra indicate<br />

the effect of the loading in the smaller or the larger micropores being not interc<strong>on</strong>nected. An<br />

increase of Pt c<strong>on</strong>tent above 1 % does not influence the propane mobilities in the Pt-loaded<br />

activated carb<strong>on</strong> and also the catalytic activities in cyclohexane dehyrogenati<strong>on</strong> to benzene. It<br />

can be c<strong>on</strong>cluded that platinum clusters prefer to be located in the narrowest micropores.<br />
