Abstract
Nanoporous membranes are widely used in various fields, such as gas separation, water purification, catalytic processes, and the use of batteries in electrodes. Nowadays, hollow carbon spheres or nanowires are attracting attention of researchers and experimenters due to high adjustability of their mechanical and chemical properties. This makes it possible, among other things, to more accurately adjust permeability of membranes created from this material for various atoms and molecules, which ensures a good degree of gas separation. The mathematical simulation of gas separation via nanocapsule and hollow nanowire porous membrane is performed. Research has shown that such membranes are able to separate He/text{CH}_4/text{H}_2/text{N}_2 gas mixtures.

Summary
Nanoporous membranes are widely used in various fields, such as gas separation, water purification, catalytic processes, and the use of batteries in electrodes. Hollow carbon spheres or nanowires are attracting attention of researchers and experimenters due to high adjustability of their mechanical and chemical properties. This makes it possible, among other things, to more accurately adjust permeability of membranes created from this material for various atoms and molecules, which ensures a good degree of gas separation. Nanocapsules, are particles of a diameter from a dozen nanometers to a millimeter[1] with a cavity inside and a thin shell (Fig. 1) This construction provides the material with attractive encapsulation capabilities, controlled permeability, surface functionality and chemical and thermal stability. The hard-template method allows efficiently adjusting the size of particles and their cavities; the process of removing the template is often complicated and not environmentally friendly
