Release of methane from nanochannels through displacement using CO.

In this work, we investigate the release of methane in quartz nanochannels through the method of displacement using carbon dioxide. Molecular dynamics (MD) simulations and theoretical analysis are performed to obtain the release percentage of methane for nanochannels of various diameters. It is found that both the pressure of CO and the channel size affect the release percentage of methane, which increases with increasing pressure of CO and channel diameter.

Effect of external pressure on the release of methane through MFI zeolite nanochannels.

In this work, the effects of external pressure on the release of methane through zeolite nanochannels are studied through molecular dynamics (MD) simulations. The release percentage of methane under three types of pressure loadings with various strengths and frequencies are obtained. Specifically, constant, sawtooth-shaped, and sinusoidal pressures are examined.

Effects of temperature and pore structure on the release of methane in zeolite nanochannels.

In this work, we investigate the effects of temperature and pore size on the release of methane in zeolite nanochannels through molecular dynamics (MD) simulations. The methane release percentage at different temperatures and for different zeolite structures is calculated. In all-silica MFI (silicalite-1) zeolite, it is found that the release percentage increases with increasing temperature roughly at a constant rate when the temperature is below 598 K.
