Abstract Zeolites and metal‐organic frameworks (MOFs) are considered as “competitors” for new separation processes. The production of high‐quality gasoline is currently achieved through the total isomerization process that separates pentane hexane isomers while not reaching ultimate goal a research octane number (RON) higher than 92. This work demonstrates how synergistic action zeolite 5A MIL‐160(Al) MOF leads to novel adsorptive upgrading an efficient isomers. innovative mixed‐bed...
Ion-exchange on bare commercial zeolites can offer improved adsorption processes. In the context of CO2/N2 separation for post-combustion CO2 capture (PCC), here, we report, effect ion-exchange binder-free NaY zeolite with alkali (K+) and alkaline earth (Ca2+) metal cations, achieving exchange levels 23 %, 58 95 % K+ 56 71 Ca2+. Adsorption isotherms N2 were measured over a temperature range 306–344 K pressures up to 350 kPa. At low pressures, capacity increases as Na+ ions are exchanged...
The improvement of the Total Isomerization Process (TIP) for production high-quality gasoline with ultimate goal reaching a Research Octane Number (RON) higher than 92 requires use specific sorbents to separate pentane and hexane isomers into classes linear, mono- di-branched isomers. Herein we report design new multi-cage microporous Fe(III)-MOF (referred as MIP-214, MIP stands materials Institute Porous Materials Paris) flu-e topology, incorporating an asymmetric heterofunctional ditopic...
Abstract The adsorption equilibrium and kinetics of CO 2 , CH 4 N on three types BETA zeolites were investigated at different temperatures a defined partial pressure range from dynamic breakthrough experiments. adsorbed amount followed the decreasing order > for all studied materials. For same ratio SiO /Al O 3 Na‐BETA‐25 zeolite showed higher uptake capacity than H‐BETA‐25, due to presence Na + cationic center. Comparing H compensation cation, H‐BETA‐25 expressed slightly H‐BETA‐150....
This study focuses on the development of a conceptual vacuum pressure swing adsorption process (VPSA) for green hydrogen (GH) recovery from natural gas grids (NGGs). Accordingly, kinetics-based separation H2 NGG was achieved by using commercial carbon molecular sieve (CMS-3K-172) adsorbent. To develop VPSA cycle, CMS-3K-172 characterized, single- and multicomponent breakthrough curves CH4 were performed, isotherms collected between 195 273 K pressures up to 18 bar. separate (20%) (80%),...
The microporous MOF MIL-140B can separate hexane isomers according to the degree of branching, linear >mono-branched >di-branched, with a remarkably high selectivity up 10 at 343 K. GCMC simulations confirm origins molecular separation.
Single- and multicomponent adsorption fixed bed breakthrough experiments of carbon dioxide (CO2), methane (CH4), nitrogen (N2) on commercial binder-free beads 4A zeolite have been studied at 313, 373, 423 K a total pressure up to 5 bar. The ternary (CO2/CH4/N2) show practically complete separation CO2 from CH4/N2 all the temperatures studied, with selectivity 313 around 24 over CH4 50 N2. equilibrium data measured were modeled by dual-site Langmuir isotherm, results simulated model taking...
The performance of porous metal organic framework ZIF-8 in the separation all five hexane isomers (nC6, 2MP, 3MP, 23DMB, 22DMB) is evaluated through a series multicomponent breakthrough adsorption experiments, at temperatures 373, 423, and 473 K up to total pressure 0.5 bar. reported data show for experiments following sorption hierarchy: nC6 ≫ 2MP > 3MP 23DMB 22DMB. At temperature 373 hydrocarbon bar mixture loading can go 2.15 mol·kg–1. In addition, same selectivities measured by ratio...

The adsorption of carbon dioxide (CO2), methane (CH4), and nitrogen (N2) has been studied on potassium-exchanged (95%) binder-free beads Y zeolite through single, binary, ternary fixed bed breakthrough experiments, covering the temperature range between 313 423 K a pressure up to 350 kPa. At kPa, single-component data obtained showed that amounts adsorbed CO2, CH4, N2 are around 6.42, 1.45, 0.671 mol kg–1, respectively. binary experiments CO2/N2 carried out under typical post-combustion...

Abstract Zeolites and Metal Organic Frameworks (MOFs) have frequently been considered as “ competitors ” for the development of new advanced separation processes. The production high quality gasoline is currently achieved through energy demanding conventional Total Isomerization Process (TIP) that separates pentane hexane isomers while not reaching yet ultimate goal a Research Octane Number (RON) higher than 92. Herein we demonstrate how an unprecedented synergistic action two complementary...
Recent breakthrough experiments revealed the iso-reticular Zr-MOFs, MIL-140B and MIL-140C, as promising sorbents for separation of C6 isomers. Interestingly while ultra-small pore exhibited hexane isomer sorption hierarchy according to normal boiling point order (n-C6 > 3MP (3-methyl pentane)), an uncommon shift in elution was observed larger MIL-140C. It only speculated that flexibility MOFs might be origin this intriguing behavior. Herein, flexible force field hybrid osmotic Monte Carlo...
