摘要：
We focus on the analysis of N-2 adsorption on NaY faujasite investigated by means of both the FTIR and volumetric measurements. We examine how these two approaches, when combined, can lead to a more advanced quantitative description featuring the understanding of gas adsorption both at the molecular and the macroscopic scales. For this task, we describe hereafter the method used and how we circumvented drawbacks encountered along the way. Finally we share new insight obtained by working step by step towards the construction of the first quantitative molecular isotherms of N-2 on a NaY zeolite.
