Research objective was studying regularities for non-stationary kinetics of the thermolysis process in multicomponent hydrocarbon environments and studying regularities of compensation effect. The object of research was chosen aromatized, aromatized and waxy and waxy tars, and also tar of mix Arlansky and West Siberian oil.

In the course of research was studied the nonstationary macrokinetics of the thermolysis process in multicomponent hydrocarbons systems, on the example of various nature straight-run oil residues of thermolysis.

Values of effective energy of activation and effective a preexhibitor in arrhenius equation for various hydrocarbonic systems are received. At temperatures of 400-425 ºС values of effective energy of activation of process is in range of 12,5 – 154,6 kJ/mol and values effective preexhibitors of ln k₀ – in the range of 0,43-25,3; at temperatures of 425-450 ºС values of energy of activation is in range of 13,4-396,9 kJ/mol and values effective preexhibitors of ln k₀ – in the range from 0,64 to 64,6.

Unlike the classical areniusovsky description of process, the non-stationary kinetics is described by one more constant which characterizes not stationarity of process and is connected with drift of a kinetic constant in time. The mathematical sense of a constant k is characterized by markovsky transitional probability. Values of effective constants for the studied raw materials are in range of 0,029 – 0,257 sec^-1 for an interval of temperatures 400-425ºС and 0,0001 – 0,7189 sec^-1 for an interval of temperatures 425-450ºС that corresponds to diffusive area.

The kinetic compensation effect is confirmed which exists in multicomponents systems and there are included linear dependence of a logarithm preexhibitors and effective energy of activation process in an arreniusovsky constant of reaction rate. Effective kinetic parameters thermolysis process are finded can be use in the engineering calculation of thermal and thermocatalytic technological processes.
