Abstract: [cze] [eng]
Práce se zabývá možností využít iontové kapaliny pro separaci oxidu uhličitého od methanu. Work deals with ionic liquid membranes for separation of carbon dioxide and methane. Main advantage of ionic liquid is negligible vapor pressure and low chemical reactivity. [1]. Selectivity of liquid membranes is given by different solubility of separated gases in chosen liquid. Carbon dioxide is twenty times more soluble in used ionic liquid than methane. Membrane used for separation consisted of porous PVDF and ionic liquid [emim][Tf2N]. Permeability of pure gases and model mixtures through the membrane was tested. Ideal selectivity of the membranes for CO2/CH4 mixture was found to be 22. Permeability of pure gases does was only about 10% higher than permeability of mixed gases. The membrane may be applied for purification of biogas.
