摘要

Abstract

This research discusses the separation of methane gas from three different gas mixtures

and CH

/CO

using a modified silicon carbide nanosheet (SiCNS) membrane using both molecular dynamics (MD) and computational fluid dynamics (CFD) methods. The research examines the effects of different structures of the SiCNSs on the separation of these gas mixtures. Various parameters including the potential of the mean force

separation factor

permeation rate

selectivity and diffusivity are discussed in detail. Our MD simulations showed that the separation of CH

and CH

/CO

mixtures was successful

while simulation demonstrated a poor result for the CH

mixture. The effect of temperature on the diffusivity of gas is also discussed

and a correlation is introduced for diffusivity as a function of temperature. The evaluated value for diffusivity is then used in the CFD method to investigate the permeation rate of gas mixtures.
