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...

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...

A site energy distribution function based on a condensation approximation method is proposed for gas-phase adsorption systems following the Toth isotherm. The proposed model is successfully applied to estimate the site energy distribution of three pitch-based activated carbons (PA, PFeA and PBA) developed in our laboratory and also for other common adsorbent materials for different gas molecule...

Developing an efficient sorbent and adopting ethylene adsorption separation unit in downstream of oxidative coupling methane (OCM) process were the main focus present study. Since mole fraction generated OCM reactor outlet is relatively low, processing cost accompanying components thereby per ton using conventional cryogenic are insupportable. Zeolite 13X was modified this research, demonstrati...

Zeolites can be used to store thermal energy, but they may age and lose a fraction of their storage capacity during prolonged use. The purpose this study is determine which parameters are responsible for the aging zeolite NaY by exposing it extreme hydrothermal conditions. In laboratory unit, fixed bed binder-free beads was treated hydrothermally, were analyzed signs aging. Also, 13X tested com...

Atmospheric water vapor extraction through adsorption to highly porous materials holds promise for its incorporation into broader technologies, including potable generation. These technologies require breakthroughs in synthesis and design. Here, we demonstrate a composite of zeolite 13X sorbent high capacity infiltrated with light-weight three-dimensional graphene binder, which effectively netw...

There is considerable interest in the use of mesoporous structures (e.g. zeolites and metal organic frameworks) for hydrogen storage but little is known about the molecular interactions and the dynamics of molecules inside the cages of these structures. In order to determine these properties we have measured the nuclear magnetic spin-lattice and spin-spin relaxation times of HD molecules trappe...
