1. 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
