- Temperature dependence of saturation loading of H2, CH4, CO2, CO and N2.
- A monovariate regression analysis of experimental adsorption isotherms.
- Langmuir and Sips models adsorption parameters of light gases in LTA 4A.
- Differences absolute and excess of loading in adsorption parameters.
The temperature dependence of saturation loading of H2, CH4, CO2, CO and N2 is evaluated for LTA 4A zeolite. For this purpose, the saturation loading is calculated at each temperature by applying a monovariate regression analysis to a number of experimental adsorption isotherms taken from previous publications in the literature within a wide range of conditions.In performing this investigation, Langmuir and Sips adsorption parameters of H2, CH4, CO2, CO and N2 are also evaluated, obtaining a satisfactorily low degree of uncertainty. This type of data, characterizing the adsorption behaviour of the considered materials are of practical importance and can be directly used by material scientists and general end-users. The role of excess and absolute loading is also discussed, highlighting that an appreciable difference is found at a relative high pressure only.
