| In the present investigation, the stability of molybdenum dioxide MoO2 has been investigated as catalyst for the steam reforming of isooctane. To achieve this, a combination of activity measurements together with XPS analysis provided information about the factors affecting the stability of the catalyst. The pressure and temperature used in this work were 750oC and 1 atm, respectively. According to our findings, if the partial pressure of isooctane is fixed to 0.03 atm, the stability of the catalyst becomes higher at steam to carbon ratios close to 1.2. In addition, the activity of MoO2 appears to be related to the presence of dual metal-acid sites, which are able to enhance the reforming process. However, the availability of these dual sites is strongly affected by gas-solid reactions, which are able to limit the amount of active sites required to stabilize the reforming process. |
