Abstract: We have investigated the catalytic properties of scheelite-type oxide Bi1-x/3V1-x-MoxO4 in the selective oxidation of propane to acrolein.When x is 0.45, the catalyst Bi0.85V0.55Mo0.45O4 shows good catalytic effect; the selectivity for acrolein is 23% at 54% conversion of propane. Monovalent silver promoter markedly improves catalytic performance of the bismuth vanadomolybdate Bi0.85V0.55Mo0.45O4. Under the optimum reaction condition. the catalyst Ag0.01Bi0.85V0.54Mo0.45O4 shows much better catalytic performance with the selectivity for acrolein being 32% at 52% conversion of propane.

Key words: propane, selective oxidation, bismuth vanadomolybdate, promoter, acrolein
