Separation of equimolar mixtures of C6 isomers (a) and C5 and C6 isomers (b) by fixed bed adsorption with MIP-214 at 373 K and a total isomers pressure of 10 kPa. Breakthrough data is plotted as the normalized molar fraction of each isomer (left y-axis) and average real-time RON (right y-axis) as a function of time.
