Pressure Swing Adsorption (PSA) technology represents an important separation process for gases. In addition to typical integration of PSA units in the plant structures (e.g. combination of steam reformer and H2-PSA) more complex combinations are possible to optimise the overall process performance. The PSA process itself is strongly influenced by certain process parameters like tail gas pressure,...
The adsorption of hydrogen on nanostructured carbons prepared by templating of mesoporous silicas has been studied at 77 K and between 0.1 and 1 MPa. The maximum capacity was obtained with a carbon synthetized by a sucrose liquid infiltration process in MCM-48 silica. It was observed that the hydrogen weight percentage which can be adsorbed on a carbon can be correlated to its microporous volume determined...
