“…The most attractive aspect of the IGC is the effective application to a wide range of physicochemical characterization of non-volatile materials such as dispersive and specific parameters of surface free energy, diffusion coefficient, phase transitions and crystallinity (Voelkel et al, 2009;Mohammadi-Jan and Waters, 2014), which can yield vital information in the fields of polymer and coatings (Edelman and Fradet, 1989;Murakami et al, 1998;Abel et al, 2002), pharmaceuticals (Grimsey et al, 2002;Planinsek and Buckton, 2003;Mohammadi-Jan and Waters, 2014) fibers (Cantergiani and Benczédi, 2002;Heng et al, 2007) or nanomaterials (Batko and Voelkel, 2007;Menzel et al, 2009). Basing on the physicochemical properties of the material introduced on the packed column, IGC can be used for the separation of paraffins, as was reported by Autie et al in previous researches using porous hexacyanocobaltates (Autié-Castro et al, 2009), metal-organic framework (Cu-BTC and Fe-BTC) or natural clinoptilolite (Rivera et al, 2011).…”

In this work the applicability of a natural volcanic glass (technological type I material) from Cuba is investigated as adsorbent for separation of mixtures of C 1 -(C 5 ; C 6 ; C 7 ; C 8 ; C 9 ) hydrocarbons by inverse gas chromatography under flow conditions in a temperature range of 328-343 K. The experimental results indicated that the material was mainly composed of silica and, in a lower proportion, of alumina, that provided surface Si-OH and Al-OH groups to favor the interaction and separation of the different components of paraffin mixtures. In fact, the calculated heats of adsorption were high enough to facilitate the separation procedure. The high availability and low cost of these materials make them potential and attractive candidates to be used in large scale applications.
