A comparative study of CeO2-Al2O3 support prepared with different methods and its application on MoO3/CeO2-Al2O3 catalyst for sulfur-resistant methanation

- A comparative study of CeO2-Al2O3 prepared with different methods is carried out.
- The catalysts whose support is prepared with DP exhibit the best activity.
- CeO2 covered on the surface of support is favorable for the catalytic activity.
- The formation of Al2(MoO4)3 and crystalline MoO3 does not favor the activity.
- CeO2 layer decreases the negative effect of calcination temperature on catalysts.
