文摘

•: A non-isothermal numerical model was developed for dual reflux pressure swing adsorption cycles.
•: Bed pressure, flow and temperature profiles from N₂ + CH₄ experiments were well matched.
•: Predicted CH₄ mole fractions had r.m.s. deviations of 0.003 and 0.024 for the light and heavy products.
•: Simulations provide insight into the optimisation of the feed step time and mass transfer effects.
