The course of non-isothermal adsorption of carbon dioxide from nitrogen stream in laboratory glass adsorbers with a polyurethane insulation, without insulation, with a vacuum silvered jacket and with a vacuum jacket with radiation curtain of aluminium sheet was investigated from the point of view of the possibility to employ a one-dimensional model to describe the adsorption course. The assumptions of the one-dimensional model are fulfilled, from the adsorbers investigated, by the adsorber with vacuum silvered jacket and the adsorber with vacuum jacket with radiation curtain.
