In order to improve the productivity and energy saving level of styrene in the dehydrogenation of ethylbenzene
optimization is an effective technological mean.The application of improved non-dominated sorting genetic algorithm is studied in optimization for operating conditions of dehydrogenation of ethylbenzene.Conversion and selectivity of the process of dehydrogenation of ethylbenzene to styrene are considered as the two objectives
and the kinetic model and process conditions are the constraints of the problems.NSGA-Ⅱ(non-dominated sorting genetic algorithm)is used to solve the optimization question of above dehydrogenation of ethylbenzene process.According to the obtained Pareto optimal solution set
the influence of operating conditions on conversion and selectivity of dehydrogenation of ethylbenzene is analyzed.Fuzzy comprehensive evaluation method is studied to satisfy specified demanding
supplying referenced optimal operating conditions.The results demonstrated good performance of NSGA-Ⅱ for achieving global optimal.With this algorithm
a satisfactory solution in different operating constraints can be obtained.
