The process of conversion of olefin into gasoline (MOG) by catalytic olefin oligomerization originated from the Mobil's methanol to gasoline process (MTG). In the present research, the single event micro-kinetic theroy is introducted to the MOG process for intrinsic kinetic modeling. As the base of kinetic model, the reaction network and the calculation of statistical thermodynamic parameters for the corresponding elmentary reactions and hydrocarbons should be achieved by the computer algorithm. The resulting reaction network, although gigantic, thus consists of a limited number of types of elementary steps based on carbocation chemistry, generally involving series of homologous hydrocarbon species. The rate coefficients of these steps are modeled based upon transition state theory, Evans-Polanyi free energy relation and thermodynamics constraints. The basic parameters in the continuity equation, i.e., the single event pre-exponential factor or frequency factor, the intrinsic activation barrier,and the transfer coefficient etc. can be determined from the experimental data using a combination of a hybrid genetic algorithm, sequential quadratic programming, and the Levenberg-Marquardt optimizer. For the complex catalystic processes, the conventional kinetic modeling would clearly lead to an unrealistic large number of rate coefficients. While the single event kinetic theory can drastically reduce the number of independent kinetic parameters to be determined from the experimental data. Moreover, the kinetic model is based upon the detailed reaction mechanim, which parameters are not depended on the feed composition, reaction condition and even the type of reactor. The MOG is an process from small molecules to large molecules with high carbon number, which is very different from the previous process applied by this theory, such as catalytic cracking and isomeriztoin etc.. The introduction of this theory to MTG will be a great extention. The resulting kinetic modeling can be the basis for the reactor design and scale-up, and the opitization of reaction condition for the commercializaion of MTG and MOG process, which as a key process is industrially explorating in our country and is an effective way to achieve the strategy of fossil energy substitution and strategy of sustainable development.
