The adsorption of vapor and gas in porous media is a very important issue regarding a large number of industrial processes such as: gas separation, membrane technology, hydrogen storage etc. The proposed research concerns the conduction of experiments and measurements on a nano-porous material which will be rotating during the adsorption process; in-situ Small Angle X-Ray Spectroscopy (SAXS) measurements will be recorded.
Despite the fact that there are many literature references concerning static adsorption with in-situ SAXS measurements, references about adsorption under rotation do not exist, due to the demand of special rotating sample cells manufacturing. However, in Hephaestus Laboratory, such a cell has already been developed and preliminary results show that rotation allows the adsorption of larger quantity of gas in comparison with static adsorption.
Throughout the research, both experiments of nitrogen adsorption and SAXS will be conducted. Concerning SAXS measurements, contrast matching technique will be applied in order to verify that the implementation of rotation during adsorption process does provide extra free space, thus increasing the adsorption capacity of the material.
