An experimental study on permeability, diffusivity, and selectivity of CO2 and CH4 through [bmim][PF6] ionic liquid supported on an alumina membrane: Investigation of temperature fluctuations effects
In order to define a new temperature correction factor in this study, accurate experimental values were presented for permeability and diffusivity of carbon dioxide and methane in imidazolium-based room temperature ionic liquid [bmim][PF6] (1-butyl-3-methylimidazolium hexafluorophosphate) immobilized on an inorganic membrane support Results were presented as a function of temperature and pressure for temperatures within 300-320 K and pressures below 50 kPa According to the literature, experimental values of permeability and diffusivity for CH4 in [bmim][PF6] vs temperature are reported for the first time in this study. Results obtained for CO2 permeability revealed good agreement with data reported by other researchers (C) 2010 Elsevier B V. All rights reserved
