The study of non-isothermal kinetics of the process of kaolin sulphatization furnacing

This study considers the non-isothermal kinetics of kaolin sulphatization process with obtaining the crude aluminium sulphate as a main product. Using the methods of non-isothermal kinetics ensures obtaining the principal kinetic constants of the process in the temperature interval 50–235 °С within the scope of one experiment. Moreover, we demonstrate that the sulphatization process proceeds in several stages and we calculate the kinetic parameters for every single stage. Through experiments performed, we obtain the kinetic equation of the process speed.
