KATALYSATOR ZUR DEHYDRIERUNG VON ORGANISCHEN VERBINDUNGEN, VERFAHREN ZU DESSEN HERSTELLUNG UND DESSEN VERWENDUNG.

摘要

Dehydrogenation catalyst, wherein the molar ratio between iron oxide providing agent and potassium oxide providing agent calculated as iron: potassium atomic ratio is in the range of from 1.5 to 60,a K2Fe12O19 phase is present in an octahedral Fe3O4 matrix, showing crystalline epitaxy between the hexagonal structure of K2Fe12O19 and the (111) planes of the Fe3O4 spinel structure, and showing intense X-ray diffraction peaks in the area of from d=12.4 ANGSTROM to d=1.60 ANGSTROM . Process for the preparation of such catalyst and process for dehydrogenation of optionally substituted alkanes into olefins.
