“…Zhao et al evaluated the adsorption of nHEX, 3MP, and 22DMB on Zn 2 (Hbdc) 2 (dmtrz) 2 (H 2 bdc = 1,4‐benzenedicarboxylic acid, Hdmtrz = 3,5‐dimethyl‐1H,1,2,4‐triazole). [ 100 ] The MOF possesses 1D channels with diameter of 6.7 Å. Single‐component vapor adsorption isotherms revealed that it adsorbs similar amounts of nHEX (13.3 wt%) and 3MP (12.1 wt%), but substantially less 22DMB (3.5 wt%). Gas chromatography measurements using a Zn 2 (Hbdc) 2 (dmtrz) 2 ‐filled column indicated that 22DMB was nicely separated from the other two isomers.…”

Microporous metal–organic frameworks for storage and separation of small hydrocarbons

Hydrocarbons are very important energy resources and raw materials for some industrially important products and fine chemicals. There is a need for the discovery of better materials that offer enhanced capacities for safe storage of hydrocarbons. Furthermore, the development of improved separation technologies will lead to significant reduction in energy requirements and costs. In this feature article, we provide an overview of the current status of the emerging microporous metal-organic frameworks for the storage and separation of small hydrocarbons.

“…gathers some data on the adsorption performance of different materials such as carbons, zeolites, MOFs, and zeolitic imidazolate frameworks (ZIFs) tested for the separation of C 6 isomers compared to those of the tannin-derived MMCs of this study[4,[20][21][22]58,65,66]. Even more, to directly compare the C 6 separation performance of the present MMCs derived from MT extract with that of MOFs used for gas separation, IAST calculations were performed using the single-component adsorption isotherms of HKUST-1, UiO-66, and ZIF-8, previously reported by Cuadrado-Collados et al[58].…”

Two micro-mesoporous carbons (MMCs): a disordered mesoporous carbon (DMC) and an ordered mesoporous carbon (OMC), synthesized by an easy, low-cost, and green method are proposed as efficient hydrocarbon sieves for the separation of C 6 isomers: n-hexane (nHEX), 2-methylpenthane (2MP) and 2,2-dimethylbutane (22DMB). Their textural characterization reveals a highly interconnected pore network within the DMC, while a reverse hierarchy of ordered mesopores only accessible through narrow micropores is found in the OMC. The pore texture strongly affects their adsorption performance by kinetic and molecular sieving effects; the narrow constrictions in the OMC allow adsorption of nHEX and partially 2MP but not 22DMB, whereas the highly connected pore network of DMC allows adsorption of the three isomers. Multi-component adsorption isotherms calculated from the single-component experimental results by ideal adsorbed solution theory (IAST) demonstrates that the OMC material has a remarkably high selectivity for the adsorption of nHEX and nHEX + 2MP from binary and ternary mixtures, respectively. To the best of the authors' knowledge, such behavior has never been reported so far for carbon materials. Hence, this study shows that tannin-derived MMCs have great potential to be used as an eco-friendly and low-cost alternative for the selective separation of di-branched C 6 isomers.
