Economical biogas direct methanation to pipeline grade natural gas via structured Ni based inverse catalyst [PDF]

open access: yesNature Communications
Biogas upgrading to pipeline-grade methane (>95% CH4) represents a critical pathway for enhancing the utilization and value of biogas. Direct methanation of biogas is promising, but due to the performance limitations of conventional nickel-based ...
