This study presents the adsorption performance indicator for the evaluation of thermal power plant CO2 capture on mesoporous graphene oxide/TiO2 nanocomposite. To begin, this adsorbent was synthesized and characterized using N2 adsorption-desorption measurements (BET and BJH methods), X-Ray Diffraction (XRD), Field Emission Scanning Electron Microsc...

The adsorption of dilute long polymers of length N dissolved in a semi-dilute solution of shorter chains of length P is considered using a scaling approach. The short chains themselves are considered as non-adsorbableTwo qualitatively different phase diagrams in the concentration adsorption-strength diagram are predicted depending on the value of N/P~. An overall concentration and chain length ...

Large-scale computational screening of thirty thousand zeolite structures was conducted to find optimal structures for separation of ethane/ethene mixtures. Efficient grand canonical Monte Carlo (GCMC) simulations were performed with graphics processing units (GPUs) to obtain pure component adsorption isotherms for both ethane and ethene. We have utilized the ideal adsorbed solution theory (IAS...

Single and ternary solute gas phase adsorption isotherms were conducted in this study to evaluate the effectiveness of a simple constant volume method, which was utilized by using Tedlar gas sampling bags as a constant volume batch reactor. For this purpose, gas phase adsorption of toluene, methyl ethyl ketone (MEK), and methyl isobutyl ketone (MIBK) on two types of activated carbons, BPL-bitum...

The adsorption capacity and selectivity of carbon dioxide and nitrogen at 298 K have been evaluated for two series of MMOFs built on metal paddle-wheel building units, including non-interpenetrated Zn(BDC)(TED)(0.5) (1), Zn(BDC-OH)(TED)(0.5) (2), Zn(BDC-NH(2))(TED)(0.5) (3), and interpenetrated Zn(BDC)(BPY)(0.5) (4), Zn(BDC)(DMBPY)(0.5) (5), Zn(NDC)(BPY)(0.5) (6) and Zn(NDC)(DMBPY)(0.5) (7) fra...

Separation of CO2 from CO2-CH4 mixtures is an important issue in natural gas and biogas purification. The design of such separation processes depends on the knowledge of the behavior of multicomponent adsorption, particularly that of CO2-CH4 mixtures. In this study, we present a series of experimental binary equilibrium isotherms for CO2-CH4 mixtures on an activated carbon at 293 K and compare ...
