✦ Synopsis

X-ray computer-tomography

has been used in the study of dynamic sorption processes on activated carbon within gas-filtering devices. The results, obtained without disturbing the sorption process, lead to information about (1) the spatial distribution of the adsorbate and (2) the sorption process as a function of time inside the gas-filter. A quantitative relation between the measured X-ray density and the gravimetrical load of adsorbate on the gas-filter was observed. For the first time, the shape of several sorption fronts was directly visualized on X-ray density-photographs taken from the original gas-filter by X-ray computer-tomography.
