Presentation transcript:

What are observed Activity depend on metal species (V> Ni> Ca > Sn calcined at 450C) - Activity was highest when having specific mixed metal oxide composition: 4.0(SnO)-1.0(Al2O3) Activity depend on the calcined temperature 4SnO-Al2O3 : negligible activity when calcined at 450C very active when calcined at 670C - There is an optimum loading (4.0(SnO)-1.0(Al2O3) metal loading 2.0mmol/g ZSM-5 was the best among 1, 2, and 3mmol/g ZSM-5
