Notizen:
An experimental and theoretical study was made of the adsorption of ethane/propane mixtures from nitrogen or helium. The study also covered the desorption of the mixtures using a purge of hot nitrogen or helium. The adsorbent was Witco JXC activated carbon. A nonequilibrium, mechanistic model was developed and was shown to represent both adsorption and desorption processes. The model utilized mixture isotherm data predicted by the Flory Huggins form of the vacancy solution model. Both adsorption and hot purge regeneration were found to be intraparticle rate controlled processes, with surface diffusion dominating the intraparticle mass transfer mechanism. The dynamic model can be used for the simulation of a variety of commercial adsorption and desorption conditions.
