| description | <p dir="ltr">The separation of C<sub>3</sub>H<sub>4</sub>/C<sub>3</sub>H<sub>6</sub> is one of the most energy intensive and challenging operations, requiring up to 100 theoretical stages, in traditional cryogenic distillation. In this investigation, the potential application of two MOFs (SIFSIX-3-Ni and NbOFFIVE-1-Ni) was tested by studying the adsorption-desorption behaviors at a range of operational temperatures (300–360 K) and pressures (1–100 kPa). Dynamic adsorption breakthrough tests were conducted and the stability and regeneration ability of the MOFs were established after eight consecutive cycles. In order to establish the engineering key parameters, the experimental data were fitted to four isotherm models (Langmuir, Freundlich, Sips and Toth) in addition to the estimation of the thermodynamic properties such as the isosteric heats of adsorption. The selectivity of the separation was tested by applying ideal adsorbed solution theory (IAST). The results revealed that SIFSIX-3-Ni is an effective adsorbent for the separation of 10/90 v/v C<sub>3</sub>H<sub>4</sub>/C<sub>3</sub>H<sub>6</sub> under the range of experimental conditions used in this study. The maximum adsorption reported for the same combination was 3.2 mmol g<sup>−1</sup>. Breakthrough curves confirmed the suitability of this material for the separation with a 10-min gab before the lighter C<sub>3</sub>H<sub>4</sub> is eluted from the column. The separated C<sub>3</sub>H<sub>6</sub> was obtained with a 99.98% purity.</p><h2>Other Information</h2><p dir="ltr">Published in: Catalysts<br>License: <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank">https://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.3390/catal11040510" target="_blank">https://dx.doi.org/10.3390/catal11040510</a></p> |
