Abstract: A process is proposed for monitoring, controlling and/or regulating reactions of a fluid reaction mixture 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 fluid reaction mixture being passed through the gaps ( 2 ), which comprises selecting as a regulation signal the temperature which is determined in one or more gaps ( 2 ), at two or more measurement points which are distributed over the height of each gap ( 2 ).

Abstract: A chemical reactor assembly has sheet metal exchanger panels (1) separated by a gap (2). The panels operate in the presence of a heterogenic particulate catalyst in a fluid medium. The reactor is regulated by variations in the temperature detected in the gap as measured at two or more measuring points at different heights.

Abstract: Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Method for preparing (meth)acrolein and/or (meth)acrylic acid by partial gas-phase oxidation of 3-4C precursors in presence of a heterogeneous, particulate catalyst (A). Oxidation is done in a reactor having 2 or more vertical thermal plates (1), arranged in parallel and with gaps (2) between them, where (2) contain the catalyst and the gaseous reaction mixture is supplied to (2). The new feature is that the method is monitored, controlled and/or regulated through one or more temperature measurements, taken in one or more (2), at one or more measuring sites, distributed over the height of each (2). An independent claim is also included for a method of incorporating temperature-measuring devices into a reactor, on the same side of the reactor as the feed line for supplying gaseous reaction mixture.
