Cost-effective adsorption of oxidative coupling-derived ethylene using a molecular sieveCost-effective adsorption of oxidative coupling-derived ethylene using a molecular sieve Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2022-10-042021enThe authors gratefully acknowledge that this research has been co-financed by the European Union and Greek national funds through the operational program Competitiveness, Entrepreneurship and Innovation, under the call Research-Create-Innovate (Project code: T1EDK_00782).The adsorption of ethylene (C2H4) from a mixture simulating the products obtained during the oxidative coupling of CH4 using a commercial molecular sieve (MOS) is investigated. A joint experimental and theoretical approach has been employed. The adsorbent's trapping capacity decreases at higher temperatures, while the breakpoint time drops when the inlet C2H4 concentration increases. The Dubinin-Radushkevich isotherm model can better describe the adsorption of C2H4 onto the MOS. Pore diffusion is the rate-determining step given that the Bangham's kinetic model was the more suitable for this adsorption process. Finally, the low activation energy obtained corroborates the predominance of physical adsorption.http://creativecommons.org/licenses/by/4.0/Chemical Engineering & Technology44112041–2048 Siakavelas Georgios I.
