Abstract

Process for evaluating the catalytic performance of a porous solid using a vapor diffusion technique, where a probe molecule and a molecule for dead-time determination is injected into a carrier gas that is then contacted with the porous solid in a vessel, where a detector analyzes the peak width and retention time of a probe molecule and the retention time of the molecule for dead-time determination in the gas exiting the vessel.
