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.

Abstract: The invention relates to a reactor having heated reactor tubes filled with a catalyst, for carrying out endothermal catalytic reactions, in particular for dehydrogenating or steam-reforming hydrocarbons. According to the invention, the diameter of the reactor tubes increases in the direction of flow. The increase can be continuous and linear, for example using a conical reaction tube, step-wise, for example using a reaction tube comprising cylindrical and conical tube sections, or nonlinear.

Abstract: In an electrode suitable for electrolysis of aqueous sodium chloride or potassium chloride solutions, at least the outer layer contains spinels, specifically a mixture of the individual spinels of iron and of cobalt, the weight ratio of iron spinels: cobalt spinels being from 30:70 to 90:10. The electrodes are produced by applying a powder mixture of iron spinel and cobalt spinel to a substrate by a plasma spraying process wherein argon is used as the plasma gas and the spraying energy is from 6 to 30 kW.

Abstract: Prodn. involves decompsn. of readily volatile cpds. of sub. -gp. VIII metals (I) (esp. Fe, Co and/or Ni carbonyls) to the elements on the acicular Fe oxide in a fluidised bed at >=decompsn. temp. The prodt. has good magnetic props., which can be adjusted easily by varying the amt. of (I), the prefd. amt. being 0.5-25% (I), together with 0.1-3% C. Decompsn. pref. takes place in the presence of an inert org. solvent (light petrol, b.pt. 60-140 degrees C) b.pt. =decompsn. temp. (I).
