The efficient separation of C2H2/CO2 is a challenging problem due to their similar physical properties. This in addition the risk explosion when pressuring C2H2 over 2.07 bar. Besides, understanding framework–guest and guest–guest interactions also critical achieving an optimal separation. Herein, we report development robust low-cost adsorbent, MIL-160(Al), with extremely high acetylene volumetric capacity 227 cm3(STP)/cm3 selectivity 7.1 under ambient conditions. We combine situ...
The highly efficient separation of CH4/N2 remains a great challenge, but it is vital to make the most diverse natural gas resources and contributes mitigating global warming. In this work, two isostructural metal–organic frameworks (MOFs), M-MA-BPY where M Co Ni, were elaborately selected synthesized serve purpose. These MOFs thoroughly characterized found have favorable framework flexibility, endowing them with narrow uniform pore networks suitable for adsorptive CH4/N2. Further studies...
The modern technology for acetylene production is inevitably accompanied by the contamination of carbon dioxide and moisture impurities. Metal-organic frameworks (MOFs), with rational configurations fluorine as hydrogen-bonding acceptor (HBA), exhibit excellent affinities to capture from gas mixtures. Currently, most research studies feature anionic groups structural pillars (e.g., SiF62-, TiF62-, NbOF52-), whereas in situ insertion into metal clusters rather challenging. Herein, we report a...
Separation of CO2 from CH4 and N2 is great significance the perspectives energy production environment protection. In this work, we report rational synthesis chabazite (CHA) zeolites with controlled Si/Al ratio by using N,N,N-trimethyl-1-adamantammonium hydroxide (TMAdaOH) as an organic structure-directing agent, wherein dependence TMAdaOH consumption on initial was investigated systematically. More required to direct crystallization CHA higher ratio. Once product larger than 24, amount...
Selective oxidative dehydrogenation (ODH) of light alkanes to alkenes over metal oxides usually obeys a redox catalysis cycle, where the release and recovery lattice oxygen play key role in catalytic performance. Therefore, it remains challenge prepare with limited reducibility, such as TiO2, dominant active component rather than support or modifier this process. Here, we find significant increase ethane ODH performance layered TiO2 (M-TiO2) catalyst, which is situ evolved from Ti3C2Tx MXene...
With the combination of two critical features from Cummer–Schurig, acoustic cloaking and scattering cancellation technique, this study reports a hybrid design for elastic cylinders using alternating layered fluids (the effective density to be anisotropic), which are achieved by alternately immersing HGM (a syntactic foam, light solid material with high sound velocity) Pb (lead, heavy material) in background fluid medium. The performance proposed is investigated both numerical simulation...
In this study, we aimed to develop an efficient medical oxygen concentrator (MOC) system with a low bed size factor (BSF) and 90–95 vol % supply. Herein, nitrogen isotherms of different zeolites such as Li-LSX, Na-LSX, K-LSX were obtained. Due the highest adsorption capacity for its kinetics was measured based on dynamic breakthrough experiments zeolite pellets diameters. Also, empirical mass transfer coefficient calculated by considering physical properties adsorbent. profiles validated...
The synthesis of metal–organic frameworks (MOFs) directly starting from biomass, making the most renewable feedstocks and allowing for coupled or continuous processing, is intriguing. interference water (vapor) greatly hinders wide utilization MOFs in, e.g., recovering ethane humid shale gas, which a critical process purifying natural gas in practical scenarios. Here, we propose concept direct ligand MOF routine, i.e., linear bioderived (furan-2,5-dicarboxylic acid), biomass source...
Abstract Zeolite FAU with tunable SiO 2 /Al O 3 molar ratio has been successfully synthesized in the absence of organic structure‐directing agents (OSDA). Specifically, addition zinc species contributes to feasible and effective adjustment framework between about 4 6 depending on amount added batch composition. In contrast, a typical OSDA such as tetramethylammonium hydroxide (TMAOH) limited effect zeolite. The role is essential for crystallization zeolite higher under particular synthesis...
To solve the problem of array detection performance in environments with mesoscale eddies, this study utilizes Gaussian eddy model to describe sound speed structure disturbed by eddies. Through numerical simulations, corresponding field is obtained, and transmission loss influenced analyzed. Furthermore, investigate relation between gain spatial correlation environments, differences vertical at different positions their effects on conventional beamforming (CBF) are studied. When source...
As modified ligands with a wide range of sources, abundant functional groups, and good biocompatibility, polymers have been widely used in the development silica-based chromatographic stationary phases.
