ABSTRACT:
A process for preparing styrene from ethylbenzene in the presence of an iron oxide catalyst is presented. The catalyst is prepared from extruded alpha-FeOOH iron oxide particles derived from scrap metal via dehydration of a yellow alpha-Fe(OOH) intermediate via the Pennniman process and devoid of bound sulfate having a median size of at least 2 microns and results in improved catalyst activity.
