WebA DRIFTS study of ethane adsorption by the univalent copper cations in Cu(I)-ZSM-5 zeolite prepared by chemical reaction of the corresponding hydrogen form (Si/Al = 150) with CuCl vapour at 573 K reveals an … WebMar 28, 2024 · The single-component adsorption of ethylene and ethane in UTSA-280 samples activated at 110, 130, 150, and 200 °C were measured. To guard against possible kinetic effects, the experiment was held at each pressure for 2 h before increasing the pressure. We will argue below that the results from these experiments, at least for …

WebSep 1, 2024 · In a first step, DFT calculations revealed the adsorption energies of reactants and products of ethane and ethene oxychlorination on the FePO 4 (1 0 2) surface (Fig. 5 a). While ethane, oxygen, and HCl adsorb relatively weakly, chlorine adsorbs strongly, indicating that chlorine will only leave the surface in form of a chlorinated hydrocarbon ... WebNov 29, 2010 · Ethane is selectively adsorbed over ethylene in their mixtures on the zeolite imidazolate framework ZIF-7. In packed columns, this results in the direct production of … WebIn the petrochemical industry, ethane/ethylene (C2H6/C2H4) separation is one of the most important processes. Herein, we reported an iron-based metal–organic framework MIL-142A for efficiently trapping C2H6 from C2H6/C2H4 mixture, exhibiting preferential adsorption of C2H6 over C2H4.
