Abstract(s)
The performance of porous metal organic framework ZIF-8 in the
separation of all five hexane isomers (nHEX, 2MP, 3MP, 23DMB,
22DMB), is evaluated through a series of multicomponent breakthrough
adsorption experiments, at the temperatures of 373, 423 and 473 K and up
to partial pressures of 0.5 bars. The reported data shows for all experiments
the following sorption hierarchy: nHEX >> 2MP > 3MP >> 23DMB >
22DMB. It is also demonstrated that the sorption of nHEX is equilibrium
based in contrast with the sorption of branched isomers which is kinetic
controlled. The experimental data is also simulated through a
mathematical model developed in MATLAB code, being the results in
qualitatively agreement. This paper shows that it possible to separate the
hexane isomers in ZIF-8 by classes linear/mono-branched/di-branched if
proper experimental conditions are set-up, being the result of importance
for the octane upgrading of gasoline.
