Abstract: A tubular reactor (1) has heat exchanger plates (2) for transferring heat. Preferred Features: The heat exchange plates are arranged vertically to the main axis of the reactor to expose openings for the reaction mixture. The plates are arranged at increasing distances apart from each other. The reactor is formed as a module which can be pushed into an outer closed reaction tube.

Abstract: The invention relates to a method for the production of maleic acid anhydride by heterogeneously catalysed gas phase oxidation in a reactor. Said reactor has a reaction mixture inlet at one end of the reactor and a product mixture outlet at the opposite end of the reactor and, within the reactor volume, a device for removal of the heat of reaction, which is arranged in the form of heat exchanger plates, with a heat exchange agent flowing through said plates.

Abstract: Catalysts (I) with a bimodal pore radius distribution and a BET surface of more than 70 m /g, containing or consisting mainly of (a) 10-99.9 wt% zirconium dioxide, (b) 0-60 wt% aluminum oxide, silicon dioxide and/or titanium dioxide and (c) 0.1-10 wt% Main Group 1 or 2 element(s), Sub-Group 3 element(s), Sub-Group 8 element(s), lanthanum and/or tin. Independent claims are also included for (i) a process for the production of (I) by mixing the catalyst components with 2-30 wt% polyamine, polyacrylate, poly-alcohol, polysiloxane and/or carbohydrate, or especially polyvinylpyrrolidone, and then calcining at above 550 degrees C; (ii) a process for the dehydrogenation of 2-16C hydrocarbons in presence of (I) and optionally in presence of water vapor.
