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 K 2 Fe 12 O 19 phase is present in an octahedral Fe 3 O 4 matrix, showing crystalline epitaxy between the hexagonal structure of K 2 Fe 12 O 19 and the (111) planes of the Fe 3 O 4 spinel structure, and showing intense X-ray diffraction peaks in the area of from d=12.4 Å to d=1.60 Å. n Process for the preparation of such catalyst and process for dehydrogenation of optionally substituted alkanes into olefins. |
