چکیده
Oxygen is one of the most important products in chemical industries. This chemical element is used in various processes such as: refinery industries, manufacturing metal and other industrial operations. For instance, oxygen with high purity is utilized in different chemical processes like: steel construction, paper industries, wastewater treatment and glass production. In 1907, oxygen was produced for the first time, when Linde built a first cryogenic distillation bed for air separation [1]. Zeolite 13X is the most commonly adsorbent used in the air separation for oxygen production. The unique properties of zeolites are originated from this fact that their surfaces are formed with negatively charged oxides. Moreover, the presence of isolated cations above their surface structure is another reason for their uniqueness. Zeolites are aluminosilicate crystallines of alkaline or earth alkaline elements such as sodium, potassium and calcium.

Abstract: Â In this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13X zeolite in a fixed-bed adsorption tower which is used to capture CO2 from both humid and dry nitrogen stream under industrial conditions. The results show that the performance of amine-grafted adsorbent and 13X zeolite is almost the same in the dry ...

In this work, SO2 adsorption on 13X and 5A was explored at different concentrations, and the results were compared to molecular simulation and models. The adsorbent saturation tests were performed at four different concentrations of 250, 500, 750, and 1000 ppm, and it was observed that saturation would take more time for higher SO2 concentrations. Grand Canonical Monte Carlo method was used for...
