RESUMO

This research consists of applying methods of global optimization for chemical equilibrium calculation and combined phases for mixtures with synthesis gas. The synthesis gas has great industrial interest, for the innumerable possibilities of various chemical composite productions. Of this form, is basic to know the thermodynamic conditions which favor the attainment of definitive product. The application of methods of global optimization has great interest for the determination of the equilibrium, a time that allows determining through in an only procedure the calculation of equilibrium and the analysis of stability of phases. As case study, the method is applied in a set of reactions that generate as product the synthesis gas. Since the reactors operate in conditions near the equilibrium, we will apply methods of similar mathematical programming differentiated to study the performance of each one.
