The catalytic process with promising prospects in engineering practice has attracted most attentions from scholars at home and abroad and became one of the key problems because of involving multiple time scales.In this project we will investigate the dynamics of catalytic reaction with different time scales，the main contents are given in the following. We will discuss all kinds of oscillations as well as the induced mechanism.Different forms of oscillations, and specially, bursting oscillation will be presented. The complexity as well as the mechanism with the interaction between different time scales will be analysed in the catalytic reaction process under the different substructures.All the bifurcation as well as its dynamical behaviors for different catalytic reactions will be explored in details, to compare the different bursting oscillation and the bifurcation mechanism. All kinds of reasonable perturbation such as external excitation and internal parameters can be considered in the catalytic process, and we will investigate the nonlinear behavior of the system under different periodic excitation.The bursting oscillation and bifurcation in the periodically disturbed reaction will be studied.The dynamical evolution with variation of parameters will be discussed to give the road to complicated oscillation. We will focus on multiple scale effect under different perturbation related to the practical reaction condition to optimize the parameters. To some extent,the project not only may enrich the bursting behaviors and mechanism of the nonlinear system with different timescales, but also can be used to serve for many aspects related to the process of catalytic reaction, such as the experiments, the design of engineering in the practice.
