Structure and dynamics of ethane confined in silica nanopores in the presence of CO₂.

ABSTRACT: Fundamental understanding of the subcritical/supercritical behavior of key hydrocarbon species inside nano-porous matrices at elevated pressure and temperature is less developed compared to bulk fluids, but this knowledge is of great importance for chemical and energy engineering industries. This study explores in detail the structure and dynamics of ethane (C₂H₆) fluid confined in silica nanopores, with a focus on the effects of pressure and different ratios of C₂H₆ and CO₂ at non-ambient temperature. Quasi-elastic neutron scattering (QENS) experiments were carried out for the pure C₂H₆, C₂H₆:CO₂ = 3:1, and 1:3 mixed fluids confined in 4-nm cylindrical silica pores at three differ
