“…Substituting the hydroxyl groups with the bulky VTMS substituent led to lower Despite the modest selectivity, the impressive resilience of CA membranes under harsh plasticizing conditions has allowed them to retain their edge in the market. Multiple studies report that CA-based membranes can maintain stable CO 2 /CH 4 performance in the face of aromatic natural gas contaminants such as toluene, benzene, and xylene [85,[93][94][95].…”

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.

“…At 298 K and 14 bar, the quantity of CO 2 absorbed by MOF-5 was reported to be as high as 48.0 wt.%. Functionalizing ligands and introducing them into open metal sites can further boost the CO 2 storage capacity of the material [ 78 ]. Permeability is the amount of gas molecules that can flow through a membrane in a unit stream.…”

“…Cellulose acetate (CA), as a porous membrane material and an important derivative of natural cellulose, has played an important role in membrane separation because of good film forming performance [1,2], high hydrophilicity, easy biodegradation and relatively low cost [3]. At present, the most common method for membrane preparation is phase-inversion method, and the membrane prepared generally present finger-like, sponge-like, or both the two porous structures.…”

As a kind of eco-friendly (biodegradable) material and with a natural anti-fouling ability, cellulose acetate (CA) is more suitable for single-use membrane (especially in bioprocess). In this study, the method for preparing CA membrane by Vapor-assisted Nonsolvent Induced Phase Separation (VNIPS) was studied. The influences of ratio compositions (solid content, acetone/N,N-Dimethylacetamide ratio, glycerol/CA ratio) and membrane preparation conditions (evaporation time, evaporation temperature and humidity) on the microstructure and other properties were systematically evaluated. Results indicated that acetone/N,N-Dimethylacetamide ratio and glycerol/CA ratio had great influence on the cross-section structure of membranes. Additionally, the membrane with homogeneous sponge-like porous structure could be prepared stably within certain limits of ratios. Under the premise of keeping the content of other components fixed, the separation membrane with a full sponge pore structure can be obtained when the ratio of glycerol/CA is ≥2.5 or the acetone/solvent ratio is between 0.25 and 0.5. Evaporation time and temperature, humidity and other membrane preparation conditions mainly affected the surface morphology and the pore size. This kind of high-performance membrane with homogeneous sponge-like pore and controllable surface morphology could be potentially used for bioseparation processes.
