Abstract: A process for the preparation of maleic anhydride by heterogeneously catalyzed gas-phase oxidation in a reactor with feed for the reaction mixture at one end of the reactor and discharge of the product mixture at the opposite end of the reactor, and with devices for dissipating the heat of reaction which are arranged in the reactor interior and through which a heat-exchange medium flows and which are designed as heat-exchanger 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.

Abstract: In a process for the recovery of a polymerizable useful fraction, consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindenes and fractions whose boiling points are between styrene and methylindenes, from the crack gases of a steam cracker, the sidestream of the crack gas column is divided, by means of a distillation unit, into the useful fraction and into fractions which are recycled to the crack gas column.
