Thermokinetic study of the reduction process of a CuO/ZnAl2O4 catalyst.

Formal kinetic analysis of reduction process of the Cu-based layered double hydroxide -- LDH catalyst precursor for methanol synthesys was implemented. The process was studied by means of thermogravimetry (TG) and Differential scanning calorimetry (DSC) with respect to changes taking place in gas phase, which was analyzed by Massspectrometry (MS). The kinetic parameters of the non-isothermal reduction were determined and the rate limiting step was found. [ABSTRACT FROM AUTHOR]
