โฆ Synopsis
We developed a detailed kinetic model for methanol conversion to hydrocarbons over zeohtes. The dimethylether at equilibrium with methanol, generates carbene; it attacks the oxygenates giving light olefins, and the latter forming higher olefins. The olefins, through carbenium ions, form aromatics and paraffins. The kinetic parameters, identified by nonlinear optimization techniques, and the model predictions, agree quite well with the experimental and literature available data.

In order to reduce a complex kinetic model (33 reactions), which describes the methanol conversion to olefins, to a model easier to use, the discretization procedure combined with the integral procedure and ridge regression analysis were used. Because few experimental data are available, new points
