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:

Improvement of hydrogen production from coal gasification for power generation application
TL;DR: In this paper, the authors presented a coal gasification model in terms of increased H 2 production and emission reduction, and the results showed that, with rising temperature, H 2 output increases from 1.78E-11 kg/hr to 2.21 kg/HR at 2,000°C while CO 2 emission dropped from 8,364.11 kg /hr to 8,027.21kg/hr.

Characteristics of CO 2 adsorption and desorption on activated carbon in comparison with zeolite 13X and carbon molecular sieve and applications in biogas upgrading using vacuum pressure swing adsorption ( VPSA )
TL;DR: In this article , the authors investigated the performance of activated carbon (AC) in CO2/CH4 adsorptive separation and showed that AC has relatively high dynamic adsorption capacity and high mass transfer coefficient of CO2 in AC.
