文摘
- •
The total number of moles of CO2 stored is unequal to CH4 recovered.
- •
CO2 storage efficiency was first discussed in terms of CH4/CO2 replacement.
- •
Two replacement methods using different experimental conditions were evaluated.
- •
Effects of the freezing point on CH4 recovery and CO2 storage were investigated.
- •
The combined method effectively improved CH4 recovery and energy efficiency.
