of experiments using Ru/Pr2O3 and Ru/Ba-Ca(NH2)2 and simulation results of a single pass over the reactor for validation based on the values in Table . In the case of Ru/Pr2O3, the simulation results approximately describe the experimental values, although the error tends to be significant at higher pressure conditions. As for Ru/Ba-Ca(NH2)2, the R 2 values of the fitting are high, and the modeling is sufficiently accurate at various reaction conditions. Thus, it was found that the Modified-Temkin model reproduces the experimental results for each of the new Ru-based catalysts, Ru/Pr2O3 and Ru/Ba-Ca(NH2)2, by parameter fitting through the least-squares method. It is the first example of modeling the reactions of Ru-based catalysts other than Ru/C with the Modified-Temkin equation, which considers the reverse reaction.
