| Abstract: | Non-isothermal experiments were conducted to study the kinetics and mechanism of the decomposition reaction of the sulface-formed sulfates for two kinds of spinel solid solutions by In situ thermogravimetric unit. Reaction mechanism functional models of reduction decomposition in spinels-formed sulfates were found. Provide a valuable theory basis for industrialize appliance of DeSOx additives. |
