Abstract
The reduction of copper oxide derived from basic Cu-carbonate in hydro gen has been studied under temperature-programmed conditions (TPR) and the TPR patterns were analyzed by means of Arrhenius plots at constan t conversion (Friedman plots). These plots indicate that the reduction process cannot be described on the basis of constant kinetic paramete rs and reveal the presence of isokinetic temperatures. These suggest t he presence of a compensation effect requiring a modification of the r ate equation.
