3022a. ----- [RUHRCHEMIE, A. G.]  [Process for Dehydrogenating Hydrocarbons With Formation of Aromatics.]  German Patent Appl. --, R 710, filed Mar. 29, 1944.  FIAT Reel K-30, frames 7,826-7,835; PB 73,587.

In the dehydrogenation of hydrocarbons with formation of aromatic compounds, so little C separates and during catalyst regeneration , so little heat of reduction generates that the total heat effect from C combustion and from reduction is consumed again during the endothermic course of the reaction.  The catalyst serves as a heat accumulator, which exchanges heat directly with the reaction gas.
