Key Points

This research aims to evaluate MFU-4 as an efficient molecular sieve for separating CO₂ from CH₄ in biogas upgrading.
Kinetic adsorption experiments were conducted using MFU-4 as the molecular sieve.
CO₂/CH₄ separation efficiency was analyzed under various conditions.
Comparison with thermodynamic methods to highlight advantages of adsorption.
MFU-4 achieved a significant CO₂ separation efficiency of 92% compared to traditional methods.
The adsorption kinetics demonstrated rapid CO₂ capture, with half-saturation time under 30 seconds.
Long-term stability tests showed minimal degradation over extended use, enhancing feasibility for industrial applications.

Implication

Demonstrates efficient CO₂/CH₄ separation in biogas upgrading, suggesting enhanced biomethane production.

Abstract

The efficient separation of CO₂ from CH₄ is central to industrial biogas upgrading for the production of pipeline-quality biomethane. Kinetic, molecular sieve–based adsorption is preferred over thermodynamic approaches, making small-pore...
