Abstract: The invention concerns a method of obtaining, from the cracked gases emerging from a steam cracker, a polymerizable fraction of recyclable material consisting of styrene, methylstyrenes, vinyltoluenes, indene, methylindenes and fractions whose boiling points lie between those of styrene and the methylindenes, a secondary stream from the cracked-gas column being divided, by means of a distillation unit, into the fraction of recyclable material and into fractions which are fed back to the cracked gas column.

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: The invention relates to the implementation of heterogeneous catalytic reactions in a moving-bed reactor. Expansion volumes for the catalyst are provided in the defining walls of the catalyst bed, said volumes being easily created by means of at least two graduated conical-or polygonal-frustrum-shaped walls. Said implementation reduces the catalyst abrasion and avoids damaging the catalyst screens.

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: The invention relates to a method for the continuous gas phase oxidation of C3- and C4-precursors to (meth)acrolein and/or (meth)acrylic acid in the presence of a catalyst, in a reactor. Said reactor has a feed element for the reaction mixture at one reactor end and a discharge element for the reaction mixture at the opposite reactor end and is equipped with devices for dissipating the reaction heat inside the reactor. A heat exchanger agent flows through said devices, which are configured in the form of heat exchanger plates.
