Abstract
The study is aiming to prepare supported ionic liquid membranes for carbon dioxide separation efficiently. The ionic liquid, [bmim][${PF_6}^-$] (1-butyl-3-methyl-imidazolium hexafluorophosphate) was fixed in the pores of PVDF micro-filtration membrane with a nominal pore size 0.1 ${\mu}m$. The permeabilities of $N_2$, $H_2$ and $CO_2$ gases through the prepared ionic liquid membrane were 0.075, 0.203 and 1.380 GPU, respectively. The selectivities of $CO_2/N_2$, $H_2/N_2$ were 14.2 and 2.69, respectively. Also, the supported ionic liquid membrane could be operated stably up to 2.0 bar with the immobilization of ionic liquid in the pores.
