Abstract(s)
The sorption of CO2 and CH4 in binderless beads of 13X zeolite has been
investigated between 313 and 423K and total pressure up to 0.5MPa through fixed
bed adsorption experiments. Experimental selectivities CO2 = CH4 range from 37 at
a low pressure of 0.0667MPa to approximately 5 at the high temperature of 423K.
The breakthrough curves measured show a plateau of pure CH4 of approximately
6min depending of the operating conditions chosen. A mathematical model was
developed and tested predicting with good accuracy the behaviour of the fixed bed
adsorption experiments being a valuable tool for the design of cyclic adsorption
processes for biogas upgrading and CO2 capture using 13X zeolite.
