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.

摘要： The invention offers an improvement in a process for start-up in the occasion of producing acrolein and acrylic acid by catalytically oxidizing propylene at vapor phase under high load conditions, the start-up meaning the step of increasing the propylene supply rate (loading) from the non-reacting condition to the prescribed reaction conditions. This process is characterized in that the propylene supply rate is increased in the start-up stage of the reaction until the prescribed composition of starting reactant gas and the flow rate of the starting reactant gas are obtained, while adjusting at least one of the reaction temperature, the composition of the starting reactant gas and flow rate of the starting reactant gas, so as to maintain the propylene conversion at not lower than 90 mol %, the maximum peak temperature of the catalyst layer in each reaction zone at no higher than 450° C., and the sum of each ΔT (maximum peak temperature of a catalyst layer—reaction temperature) at the catalyst layer in each of the reaction zones to be no more than 180° C., respectively. According to this process, the reaction speedily reaches the steady state (standard operating conditions) and a high acrolein and acrylic acid yield is stably achieved from the start of the reaction.
