The single-event kinetic modeling approach is applied to olefins cracking. Experimental data from the literature are used for model development and identification of the reaction pathways in olefins cracking. A detailed product spectrum from a 1-hexene feed on ZSM-5 gives insight into the reactivity through the fractions of 20 different product olefins and the combined (C7C12=)-C-= olefins. The reaction network comprising all possible elementary reactions on ZSM-5 is generated using a matrix notation. Single-event rate constants for cracking and isomerization of 1-hexene are determined from parameter estimation. The results show the capability of the modeling approach to reproduce the complex product distribution observed on ZSM-5.
