The method has also been applied (183) to the results of Winslow and Bell (187) for similar curves over Ru/Si02. The existence of three types of carbonaceous intermediates on Ru has been confirmed by Duncan et al... 

In the above expression, [TOC j is the asymptotic residual organic carbon, which cannot be oxidized (Rcl) further. Agreement between the experimental data for combined thermolysis, catalytic, and non-catalytic WO and the model prediction is shown in Figure 5.5. From this plot one can conclude that the oxidation progress is terminated once the catalyst is deactivated due to the adsorption of carbonaceous intermediates on its surface. However, for practical design purposes one should use the lump kinetic approach based on the triangular reaction scheme such as depicted in Figure 5.1. It is believed that the rate laws can be expressed mostly by a simple power function.
