Identification of kinetics models for non-isothermal decomposition of solids from thermogravimetric analysis: kinetic analysis of chitin of shrimp shell from Black Sea

An approach for the kinetics of non-isothermal kinetic analysis of complex solid systems is proposed. A thermal analysis of the decomposition of chitin isolated from Black Sea shrimp shells was conducted. The breakdown processes of a complex solid state were investigated. Correlation dependencies for a rough solution of the Arrhenius integral were applied to study the kinetics of decomposition. To evaluate the accuracy of this process, a complex criterion was used. The results helped us conclude that real adequacy is achieved by decomposition into four subprocesses. Digestion identification results were examined.
