Considered the chemical-technological system of catalytic cracking of hydrocarbons. For modeling is selected, the part, which includes Elevator-reactor, desorber, regenerator, the furnace, a mixer and a compressor. Describes the steps for creating a simulation model. Shows the possible control and controlled variables, as well as the disturbing influence. Describes the schemas that are designed to identify exposure pathways between variables in each of the technological equipment of the system. The necessity of accounting for simulation availability recycling, which are connected with the necessity of restoration of properties of the catalyst involved in the process of catalytic cracking. Proposed method for identifying the channels of the impact of a technological system that are difficult to discover experimentally or on the basis of analytical models. Method involves comparing the reactions of the two models on the same input signal. One model describes a set of channels in the technological system as a single consolidated feed. This model can be presented as analytical expressions or obtained experimentally. The second model is the result of the decomposition of the first is the basic exposure pathways, United in a certain way. Shows that by comparing the reactions of both models, you can identify exposure pathways that are not available for study in other ways. Having been a model of basic sections of technological system, you can create a simulation model of automated technological complex, consisting of the most important devices and automatic control systems. The simulation was made, in the mathematical package MatLab + Simulink, which allows you to create and explore the structural models of objects and systems. The developed simulation model is designed to study the efficiency of automatic controlling systems of catalytic cracking processes, optimization of process parameters, personnel training.
