Fractional Order Modelling of Zero Length Column Desorption Response For Adsorbents With Variable Particle Sizes
(Sciendo, 2013) Tenreiro Machado, J. A.; Zaman, Sharif F.; Baleanu, Dumitru; 56389
This manuscript analyses the data generated by a Zero Length Column (ZLC) diffusion experimental set-up, for 1,3 Di-isopropyl benzene in a 100% alumina matrix with variable particle size. The time evolution of the phenomena resembles those of fractional order systems, namely those with a fast initial transient followed by long and slow tails. The experimental measurements are best fitted with the Harris model revealing a power law behavior.

Measurement of para-xylene diffusivity in zeolites and analyzing desorption curves using the mittag-leffler function
(Walter De Gruyter GMBH, 2016) Zaman, Sharif F.; Baleanu, Dumitru; Petras, Ivo
The new fractional calculus modeling based on Mittag-Leffler function has been employed to generate a better fit model to analyze the ZLC desorption curves for para-xylene diffusion in ZSM-5 zeolites. The diffusivity values generated herewith at 100, 125 and 150 degrees C are reported as 4.4 x 10(-13), 4.98 x 10(-13) and 5.2 x 10(-13) m(2)/s, respectively. The activation energy for this diffusion process is found 4.2 kJ/mol and diffusion proportional constant (D-0) is 1.85 x 10(-12) m(2)/s. The simplified model for ZLC response can be a better way to treat desorption data in ZLC experiments.
