A high activity and high stability iron oxide based dehydrogenation catalyst having a low concentration of titanium and the manufacture and use thereof

摘要

A high activity and high stability dehydrogenation catalyst, its manufacture and its use. The catalyst comprises an iron ox:de component having a low titanium content, wherein the iron oxide component is made by the heat-treating of a yellow iron oxide precipitate made by precipitating from a solution of an iron salt the yellow iron oxide precipitate and, optionally, an additional dehydrogenation catalytic component, wherein the iron oxide based dehydrogenation catalyst composition has a low concentration of titanium. The low titanium containing iron oxide based dehydrogenation catalyst is used in the dehydrogenation of dehydrogenatable hydrocarbons.
