Attrition resistant bulk iron catalysts and processes for preparing and using same

An attrition resistant precipitated bulk iron catalyst is

prepared from iron oxide precursor and a binder by spray drying.

The catalysts are preferably used in carbon monoxide hydrogenation

processes such as Fischer-Tropsch synthesis. These catalysts are

suitable for use in fluidized-bed reactors, transport reactors and,

especially, slurry bubble column reactors.
