摘要： Conventional gas-phase catalytic oxidation reaction apparatus comprising two reactors for production of acrylic acid is subject to problems of high equipment costs for the reactors and piping, necessity for wide installation area and easy accumulation of carbides generated by autoxidation of acrolein. On the other hand, conventional reaction apparatus comprising a single reactor has the drawbacks that the composition of gas in the first stage reaction and in the second stage reaction cannot be optimized independently of each other, and that the allowable concentration of starting propylene is limited because of the risk of explosion. As a reaction apparatus to solve these problems, this invention provides a fixed bed shell-and-tube reaction apparatus comprising a single reactor, characterized in that the inside of the reactor is divided into two reaction zones of the first reaction zone and the second reaction zone, and that a space equipped with a mechanism for introducing a gaseous substance from outside is provided between the two reaction zones.

摘要： The fixed-bed reactor of the present invention which solves the above problems is a fixed-bed reactor comprising: a first catalyst layer filled with a first catalyst for producing acrolein from propylene; a second catalyst layer filled with a second catalyst for producing acrylic acid from acrolein; and an inert substance layer provided between the first catalyst layer and the second catalyst layer, and filled with an inert substance of a cylindrical shape having a surrounding wall in which an opening is formed. The process for producing acrylic acid of the present invention is a process for producing acrylic acid comprising the step of producing acrylic acid from propylene by using the fixed-bed reactor of the present invention. According to the present invention, since the inert substance of a cylindrical shape having a surrounding wall in which an opening is formed is used as an inert substance, increase of a pressure loss can be drastically suppressed, degradation of the catalyst due to by-produced high-boiling substances and the like can be suppressed, and further the yield of acrylic acid can be enhanced, as compared with the case of using conventional inert substances. Accordingly, it is possible to produce acrylic acid at a high yield stably for a long period.
