Separation of CH4/CO2/N2 mixtures by layered pressure swing adsorption for upgrade of natural gas
TLDR
In this article, a layered pressure swing adsorption (LPSA) process is proposed to selectively remove carbon dioxide and nitrogen from low and medium natural gas flowrates, which is composed of a zeolite 13X to selectively removing carbon dioxide followed by a layer of carbon molecular sieve 3K to make the separation of nitrogen from methane.About:

Optimal design and control of pressure swing adsorption process for N2/CH4 separation
TL;DR: In this article, a two-bed, six-step PSA system aimed at heavy component CH4 upgrading is presented, where the key optimization objective is to enhance product CH4 recovery while achieving a closed-loop productCH4 purity of 75% for separating 68%N2/32% CH4 feed under external disturbances.

Sustainable nanoporous carbon for CO2, CH4, N2, H2 adsorption and CO2/CH4 and CO2/N2 separation
TL;DR: In this paper, the porosity, morphology, and composition of the nanoporous carbons were investigated and compared with those of commercially available activated carbon, which implies that the composition of prepared carbon materials plays a significant role in their CO2 adsorption and separation ability, rather than their textural properties.
