Abstract
The role of the surface area in the phase transition is discussed and a comparison is made with the La2O3 material since with this material there is no phase transition. In order to gain a better understanding of the reaction scheme the effect of residence time was studied for both cubic and monoclinic Sm2O3 and La2O3. For Sm2O3 it was found that the specific activity to C2 products based on the surface area of the cubic phase is much higher than that of the monoclinic phase. Sintering caused deactivation of La2O3 catalysts. The surface area was found to be an important factor in determining the C2 production of the catalyst.
