| Abstract: | Vanadium\|magnesium oxide(V\|Mg\|O)catalysts used for the production of butadiene from butane via oxidative dehydrogenation were made. m (V 2O 5)/ m (MgO) and catalysts calcination temperature had large effects on conversion and selectivity. 24\|V\|Mg\|O catalyst showed high activity and high selectivity for butene and butadiene while the reaction temperature was 873 K and the feed ratio n (C 4H 10 )/ n (O 2)/ n (N 2) was 4/8/88, yield of C 4 of 32% was obtained. When oxygen partial pressure decreased, the selectivity of C 4 increased; but conversion decreased. When the reaction temperature increased, the conversion and yield increased. |
