3.6 O 2 Reduces Carbon Deposition on the Catalyst
Similar to the effect of temperature, adding O 2 also reduces the carbon deposited on
the catalyst (Fig. 14 and Table 5). However, a significant amount of solid-carbon is
still present on the catalyst at a reaction temperature of 600 °C. The decrease in
