Abstract
Description
Tikhonov regularization, which is a new technique for converting time-concentration data into concentrationreaction
rate data, was applied to the kinetic analysis of n-hexane aromatization on Platinum/Alumina Catalyst.The
technique was used for the conversion of the experimental concentration-time data to rate-concentration data. Due to
the ill-posed nature of the problem of obtaining of reaction rates from experimental data, conventional methods will
lead to noise amplification of the experimental data. Hence, Tikhonov regularization technique is preferably
employed because it is entirely independent of reaction rate models and it also manages to minimize noise
amplification, thus, leading to more reliable results. The kinetic parameters obtained by the application of the
Nelder-Mead simplex optimization technique to formulated mechanistic models was used to discriminate among
rival kinetic models based upon physicochemical criteria and thermodynamic tests to give the rate of conversion of
adsorbed hexene-1 to adsorbed methylcyclopentane when hydrogen is adsorbed as a bi-molecular specie as the rate
determining step.
