Isothermal kinetics of reduction and carburization of WO3–NiO nanocomposite powder by CO/CO2

Reduction and carburization behavior of composite oxide powder of WO3–NiO by CO/CO2 was studied. And also for these reactions, the kinetics was investigated using isothermal thermogravimetric analysis technique under various CO/CO2 ratios and temperatures. The reaction products were analyzed by XRD, TEM and SEM. The effect of CO fraction was investigated at constant temperature (950 °C), to obtain an optimum value that results in complete …
