    • An object of the present invention is to provide a catalytic gas phase oxidation reaction in which: even under reaction conditions of a higher gas pressure, a higher concentration of the raw material gas and a larger space velocity of a reaction gas, the thermal accumulation at the hot spot portion can be sufficiently suppressed with ease and at low costs, so that the reaction can be continued for a long time while a high yield is maintained. As a means of achieving this object, a catalytic gas phase oxidation reaction according to the present invention is a catalytic gas phase oxidation reaction with molecular oxygen or a molecular-oxygen-containing gas by using a fixed-bed multitubular reactor packed with catalysts; with the catalytic gas phase oxidation reaction being characterized in that: a catalyst-packed layer of each reaction tube of the reactor is divided into at least two reaction zones in a tubular axial direction; and the packing of the catalysts is such that the occupation volumes of the catalysts differ between at least two of the reaction zones and that an inert substance molding is mixed in at least one of the reaction zones.
    • 本发明的目的是提供一种催化气相氧化反应,其中即使在较高气体压力,较高浓度的原料气体和较大的反应气体的空间速度的反应条件下,热累积在 可以容易地且低成本地充分地抑制热点部分,使得反应可以长时间持续,同时保持高产率。 作为实现该目的的手段,本发明的催化气相氧化反应是使用填充有催化剂的固定床多管反应器进行与分子氧或含分子氧气体的催化气相氧化反应, 催化气相氧化反应的特征在于:将反应器的每个反应管的催化剂填充层分成至少两个沿管轴方向的反应区; 并且催化剂的填充使得催化剂的占有体积在至少两个反应区之间不同,并且惰性物质模制品在至少一个反应区中混合。
