- the invention used for the catalyst raw material is described.
- the optimum activity of the catalyst (conversion rate of the raw material) varies depending on the reaction conditions (space velocity, raw material gas molar ratio, reaction tube diameter, etc.). If the catalytic activity is too strong, the methacrylic acid yield decreases due to the progress of the sequential oxidation reaction. On the other hand, if the catalytic activity is too weak, the reaction bath temperature will not rise and it will not be able to withstand prolonged use. Therefore, the establishment of a method for controlling the catalytic activity is also required to cope with many reaction conditions.
- Patent Document 5 a plurality of catalysts having different activities are activated from a raw material gas inlet side to an outlet side in a plurality of reaction zones provided by dividing the reactor into two or more layers in the tube axis direction. A method of filling so as to be higher is described. As a result, heat generation in the reactor can be suppressed to some extent, but the catalyst filling operation becomes complicated.
- the ability to perform the reaction by charging two kinds of catalysts whose catalytic activity is controlled by controlling the amount of antimony. When these catalysts are used in a single layer, the amount of antimony is reduced.
