Evaluation of Co2 and Ch4 Adsorption on Large-Pore Zeotype Titanosilicate

Ets-10, as a large-pore zeotype, was synthesized, characterized and employed to study the co2 and ch4 adsorption behavior# equilibrium isotherms of as-synthesized and k-ets-10 were measured over a pressure range of 0-100 kpa at 298k# high performance of co2/ch4 was observed over ets-10 adsorbents# kinetic parameters of co2 were extracted by fitting the experimental data by isothermal and non-isothermal models# the results revealed that both as-synthesized and k-ets-10 adsorbents are highly qualified to be used in co2/ch4 separation# after ion-exchange with k+, the equilibrium and kinetic properties of adsorption have changed# k+ with higher polarisability increases the adsorption amount and also as bigger cation decreases the diffusion time constant#
