ABSTRACT |
The effect of oxygen in carbon dioxide reforming of methane to eliminate the green house gas over a Rh(5 wt%)/Al203 catalyst was discussed based on the results of reaction in a fixed bed reactor under atmospheric condition and also on analysis results by SEM, FT-IR, and XRD. The added oxygen with 6.0 mol% of the feed did not only enhance the catalytic activity, but also seemed to almost completely prevent the carbon deposition on the Rh(5 wt%)/Al203 catalyst surface. It could be suggested that the oxygen stimulates redispersion of Rh by providing oxidative atmosphere. |
