    摘要： An object of the present invention is to provide: a catalyst for production of acrylic acid which is a catalyst usable for production of acrylic acid and is excellent in the catalytic performances such as catalytic activity and in the physical properties such as physical strength of the catalyst itself; and a process for production of acrylic acid using this catalyst. As a means of achieving this object, a catalyst for production of acrylic acid according to the present invention is a catalyst obtained by drying a mixed liquid of starting materials including molybdenum and vanadium as essential components to give a dried material, molding the dried material with a liquid binder, and calcining the resultant molding, with the catalyst being characterized in that an ignition loss ratio of the dried material is from 5 to 40% by mass. A process for production of acrylic acid according to the present invention comprises the step of: subjecting acrolein to a catalytic gas phase oxidation in the presence of a molecular oxygen, with the process being characterized in that the above catalyst for production of acrylic acid according to the present invention is used.

    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.
