“…The separation performance for the separation of toluene, cyclohexane, and isopropanol from N 2 by the OMSR membrane M3 was compared with different membranes reported in the literature, ,− as listed in Table . From Table , the permeabilities of toluene and cyclohexane through OMSR membrane M3 increased by 2.8 to 4.0 times and 1.3 to 1.5 times and selectivities of toluene/N 2 and cyclohexane/N 2 increased by 1.8 to 3.0 times and 1.5 to 1.6 times, respectively.…”

Membranes made of polyoctylmethylsiloxane (POMS) have emerged as an attractive alternative for volatile organic compound (VOC) separation and recovery. We developed an octyl-modified silicone rubber (OMSR) membrane for VOC/N 2 separation by a novel strategy. The OMSR membrane was made via the side-chain cross-linking of the poly(vinylmethylsiloxane) and a tailored octyl-grafted poly(hydromethylsiloxane). The octyl side chains were enriched around the cross-linking points composed of the supramolecular structure with octyl-rich parallel polysiloxane domain, which determined the selective transport of VOCs relative to N 2 . Compared to membranes without octyl, the OMSR membranes exhibited excellent thermal and mechanical stability and simultaneously high permeability and selectivity in VOC/N 2 separation, e.g., with >70,000 Barrer of permeability (5.7 times higher) and >240 (3.5 times higher) of selectivity with toluene/N2. We demonstrated that this unique structure has the potential to overcome the permeability−selectivity trade-off relationship, producing a promising class of membranes for removal of VOCs.

“…This can be accomplished by calculating the distance (Ra) of the polymersolvent system (Eq 1); and its ratio with respect to the interaction radius (R 0 ), known as the relative energy distance (RED) (Eq 2). When RED ≤ 1, then the polymer will dissolve in the given solvent (Hansen, 2007;Jirsáková et al, 2021). This theory considers three components: δh, which accounts for the energy arising from hydrogen bonding between molecules; δp, which corresponds to the energy contribution from dipolar intermolecular forces; and δd, representing the energy associated with dispersion forces; δ…”

Natural gas, an important source of hydrogen, is expected to be crucial in the transition to a hydrogen-based economy. The landscape of the gas processing industry is set to change in the near future with the development of highly acidic sour gas wells. Natural gas purification constitutes a major share of the gas separation membrane market, and the shift to low-quality sour gas wells has been mirrored in the trends of membrane material research. Purification also constitutes the major portion of the cost of natural gas, posing implications for the cost of hydrogen production. This review provides an update on the current state of research regarding polymeric membranes for H2S removal, along with CO2 separation, from natural gas that is used for hydrogen production via steam methane reforming. The challenges of adapting polymeric membranes to ternary H2S/CO2/CH4 separations are discussed in detail. Key polymeric materials are highlighted, and the prospects for their application in H2S removal from natural gas are evaluated. Finally, the growing interest in H2 production from H2S is discussed. Advances in the membrane industry and the emergence of new membrane materials may significantly improve the commercial viability of such processes.
