摘要： A process for producing acrylic acid through vapor-phase catalytic oxidation of acrolein or acrolein-containing gas with molecular oxygen or a molecular oxygen-containing gas using a catalyst-filled fixed bed shell-and-tube reactor is provided, which is characterized in that plural catalysts of different activity levels which are prepared by changing the kind and/or amount of alkaline metal(s) therein are filled in the reaction tubes in such an arrangement that the activity levels rise from the gas-inlet side toward the gas-outlet side of said tubes. According to this process, not only yield and productivity of acrylic acid are improved but also excessive heat, accumulation in the catalyst layer can be inhibited and catalysts degradation under heat is prevented, resulting in prolongation of catalyst life.
