Description
Summary: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 were generated using either the cubic spline approximation, or the extended model prediction, identified with a nonlinear regression procedure. The latter alternative, although it requires more computational effort, is also recommended for a subsequent kinetic analysis. The final refinement of the simplified model parameters may be accomplished by a multimodal optimization procedure.
