Реферат: We studied the kinetic model that predicted the isothermal oscillations in methane oxidation over Ni. Using the quasi-steady-state approximations we showed that in some neighbourhood of the limit cycle the reaction mechanism and the kinetic model can be simplified up to the system of only three ordinary differential equations. We also used this approach to study the self-sustained oscillations in the oxidation of ethane and propane over Ni, and we managed significantly reduce the number of equations in the model. Taking into account both initial and simplified kinetic models, we developed the mathematical models described dynamics of the partial pressures as well as the catalyst temperature in the CSTR reactor. The results of mathematic modelling of the oscillatory behaviour in the oxidation of propane over Ni are presented now .
