Abstract
A reactor for producing acrolein and/or acrylic acid from propylene comprises an inlet for propylene to enter the reactor, an outlet for reaction products to exit the reactor, and a catalyst bed disposed between the inlet and the outlet. The catalyst bed comprises a molybdenum and bismuth based mixed oxide catalyst. The catalyst closest to the inlet of the reactor, CATinlet, produces a lower amount of maleic anhydride to the total amount of acrolein and acrylic acid compared to the catalyst closest to the outlet of the reactor, CAToutlet.
