چکیده

Nanoporous graphene membranes have drawn special attention in the gas-separation processes due to their unique structure and properties. The complexity of physical understanding such membrane designs restricts widespread use for applications. In present study, we strive propose promising face this technical challenge. regard, investigated permeation separation mixture adsorptive gases CO2 CH4 through a two-stage bilayer sub-nanometer porous design using molecular dynamics simulation. A CH4/CO2 gashouse with 80 mol% composition was generated benchmarked force-fields forced cross by constant piston velocity. Three chambers are considered be feeding, transferring, capturing examine molecules under effect membrane. main objective is investigate multistage simultaneously. while crossing significantly influenced pore offset distance (W) interlayer spacing (H) nanoporous Linear configurations (W = 0 Å) those 10 Å 20 were examined varying between 8 Å, 12 16 Å. inline configuration an most effective among terms optimum performance high permeability. Furthermore, increasing results bulk-like behavior rather than membrane-like behavior, indicating parameters selectivity permeation. Our findings appropriate gas mixtures testing novel configurations.

Gas Separation through Bilayer Silica, the Thinnest Possible Silica Membrane.

Membrane-based gas separation processes can address key challenges in energy and environment, but for many applications the permeance and selectivity of bulk membranes is insufficient for economical use. Theory and experiment indicate that permeance and selectivity can be increased by using two-dimensional materials with subnanometer pores as membranes. Motivated by experiments showing selectiv...

Application of Functionalized Graphene Oxide Nanosheet in Gas Separation

   Graphene oxide nanosheet (GONS) can be a suitable membrane for gas separation with high permeability and selectivity. Separation of N2/CO2 using functionalized GONS was investigated by molecular dynamics simulations. The simulated systems were comprised of two types of GONS with a pore in their center, N2 and CO2 molecules. The selectivity and ...

Insights into CO2/N2 separation through nanoporous graphene from molecular dynamics.

We show from molecular dynamics simulations that porous graphene of a certain pore size can efficiently separate carbon dioxide from nitrogen with high permeance, in agreement with the recent experimental finding (Koenig et al., Nat. Nanotechnol., 2012, 7, 728-732). The high selectivity is reflected in the much higher number of CO2 passing-through events than that of N2 from the trajectories. T...

Efficient designs for constrained mixture experiments

Many practical experiments on mixtures (where the components sum to one) include additional lower or upper bounds on components, or on linear combinations of them. Usually theory cannot be used to obtain a good design, and algorithmic methods are necessary. Some of the available methods are discussed. Their performance is evaluated on some examples, and the form of the optimal design is investi...
