Macrokinetics and procedures for treatment of experimental data in simulating certain high-temperature chemical processes

Previously published data have been correlated with the use of similitude-theory methods for treating the experimental data, with the aim of subsequent simulation of certain high-temperature chemical processes. It has been shown that, in all of the cases considered for homogeneous and heterogeneous conversions of various hydrocarbon feedstocks, the yield of the principal products and the degree of conversion (each expressed in dimensionless form) can be defined in the form of a simple function of a criterion of motion (Re) and two or three other dimensionless groups characterizing the temperature, concentration, and geometric similarity of the model and the object being designed.
It has been shown that the proposed method can be used to simulate processes taking place in reactors differing in scale and in principle of action, in the conversion of individual hydrocarbons and mixtures of hydrocarbons, including crude oil. It has also been shown that the simulation method is applicable to both thermal and catalytic processes (pyrolysis, catalytic cracking, reforming, isomerization, etc.). The use of even the simplest computers will not only speed up the calculation, but also increase the accuracy.
