Key Points

To develop effective granular carbon adsorbents for methane adsorption and methane/nitrogen separation.
Synthesis of nitrogen and oxygen-doped microporous carbon granules
Assessment of methane adsorption capacity
Evaluation of methane/nitrogen separation efficiency
Enhanced methane adsorption observed with doped carbon granules
Improved separation performance compared to standard adsorbents
Suggests potential for increased efficiency in coal-bed methane utilization

Implication

Novel carbon adsorbents enhance methane adsorption and separation from low-concentration coal-bed methane, suggesting improved utilization methods.

Abstract

Developing novel granular carbon adsorbents for CH4 adsorption and CH4/N2 separation is always a great challenge in the utilization of low-concentration coal-bed methane (CBM). Herein, the N&O-doping and microporous carbon...
