This paper focuses on identifying the cost limits of two single-stage pressure–vacuum swing adsorption (PVSA) cycles for post-combustion CO 2 capture if “ideal” zero-cost adsorbent can be discovered. Through an integrated techno-economic optimisation, we simultaneously optimise properties (adsorption isotherms and particle morphology) process design variables to determine lowest possible avoide...

Adsorption-based processes using metal-organic frameworks (MOFs) are a promising option for carbon dioxide (CO2) capture from flue gases and biogas upgrading to biomethane. Here, the adsorption of CO2, methane (CH4), nitrogen (N2) on Zn(dcpa) MOF (dcpa (2,6-dichlorophenylacetate)) is reported. The characterization by powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), N2 physisor...

Electrothermal Swing Adsorption (ESA), or Joule-Effect heating of adsorbents in a cyclic adsorption process, is an energy-efficient technology on which to base a regenerative protective filter system. In an attempt to define the performance envelope of ESA systems, we evaluated three different ESA media: Activated carbon fiber cloth (ACFC), Carbon Fiber Composite Molecular Sieve (CFCMS), and Mi...

The pressure swing adsorption (PSA) process, is a novel method for the purification and production of bioethanol. A highly non-linear rigorous model implemented to simulate cyclic dynamics PSA, achieving purity 99% wt ethanol, which meets international standards be used as fuel. contribution this work focuses on obtaining an identified capable capturing important PSA process (with fit ab...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

We investigate the potential of a class of recently discovered metal-organic-framework materials for their use in temperature swing adsorption (TSA) processes for CO2 capture; the particularity of the considered materials is their reversible and temperature dependent step-shaped CO2 adsorption isotherm. Specifically, we present a comprehensive modeling study, where the performance of five diffe...

Carbon capture in post-combustion flue gases is vital on the grounds that most of energy requirement world supplied by non-renewable sources. Biomass-based CO2 adsorbents are interest due to their high potential adsorption capacity and contribution sustainable circular economy. In current study, Temperature Swing Adsorption (TSA) Vacuum (VSA) configurations were carried out evaluate performance...
