Abstract

Tikhonov regularization, which is a new technique for converting time-concentration data into concentration-reaction 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
