摘要： A process is proposed for preparing (meth)acrolein and/or (meth)acrylic acid by partially oxidizing C 3 and/or C 4 precursor compounds in the gas phase in the presence of a heterogeneous particulate catalyst, in a reactor having two or more thermoplates ( 1 ) arranged vertically and parallel to each other while in each case leaving a gap ( 2 ), the heterogeneous particulate catalyst being installed in the gaps ( 2 ) and the gaseous reaction mixture being passed through the gaps ( 2 ), which comprises monitoring, controlling and/or regulating the process by selecting as a monitoring, control and/or regulation parameter one or more temperatures which are measured in one or more gaps ( 2 ), at one or more measurement points which are distributed over the height of each gap ( 2 ).

摘要： The invention relates to a method for monitoring, controlling and/or regulating the reactions of a fluidic reaction mixture in the presence of a heterogenic particulate catalyst in a reactor, using two or more vertical thermal sheet metal sheets (1), positioned in parallel and separated by a respective gap (2). The gaps (2) contain the heterogenic particulate catalyst and are traversed by the fluidic reaction mixture. The invention is characterised in that the regulation signal is the temperature, which is determined in one or more gaps (2), at two or more measuring points that are distributed over the height of each gap (2).
