The presence of H2O in postcombustion gas streams is an important technical issue for deploying CO2-selective adsorbents. Because of its permanent dipole, H2O can interact strongly with materials where the selectivity for CO2 is a consequence of its quadrupole interacting with charges in the material. We performed molecular simulations to model the adsorption of pure H2O and CO2 as well as H2O/...

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 ...

polyurethane/zeolite 13x nanocomposite films were fabricated using solution casting method. the synthesized nanocomposite films were structurally characterized using sem, tga and tensile analysis. sem images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

In this work, zeolite 13X with porosity structure has been used as an adsorbent for adsorption of CO2 flue gas. The effect of operating conditions including pressure and time on adsorption capacity were investigated. The experiments conditions are constant temperature, the range of pressure 1 - 9 bar and the registration of adsorption capacity with passing of time. Experimental data were adjust...

A non-thermal plasma (NTP) discharge is used in this study for the activation and regeneration of MS-13X pellets packed a & glass beads bed dielectric barrier (DBD) reactor. NTP (in-situ) efficiently removes adsorbed carbonaceous compounds moisture resulting an improved VOC adsorption. In addition, exposure cycled storage (CSD) removal from air. The amount toluene, products formed surface bulk ...

This paper focuses on the laboratory experiments of low-temperature adsorption CO2 at elevated pressure and validation our mathematical model with data obtained. The numerical approach uses fitting isotherm parameters sensitivity analysis influencing breakthrough curve shape onset time. We first evaluate results for zeolite 13X. Then, we use obtained to design a dynamic predict profile. Experim...

This work presents a detailed parametric experimental on the feasibility of microwave regeneration two commercial adsorbents in dynamic carbon capture swing adsorption system. A synthetic flue gas (15% v/v CO2 N2) dry or with 15% relative humidity was selected, along Norit R2020CO2 activated and zeolite 13X. purpose-modified apparatus used to compare microwave-assisted conventional thermal rege...
