description: The main goal of the work is to study the method of oxygen microcalorimetry, evaluate the results for the entire range of sample heating rates, and conduct experiments with various substances that have a different number of extrema in the graphs of the dependence of the heat release rate on temperature. Also, a study was made of the quality of the device, by calibrating the sensors and measuring the noise level. The measurements were made with a flow meter and the validity of the coefficients was evaluated in the software associated with the MCC calorimeter. In the work, the kinetic parameters for two substances were obtained on the basis of the n-th order reaction for one substance and on the basis of three parallel reactions of the n-th order for the second. In addition to the study, a brief guide and analysis of the various parameters and functions of the data processing software is presented. As a result of the obtained data, it is possible to draw a conclusion about the kinetics of the pyrolysis process and further use of these results for practical purposes.
