A process for the preparation of a packed bed comprising an iron enriched cobalt catalyst for use in a Fischer-Tropsch reaction, the process comprising the steps of: (a) providing a packed bed with one or more catalyst particles comprising metallic cobalt; (b) contacting a part of the catalyst particle(s) in the packed bed with an iron containing compound. The process is preferably conducted in situ which conveniently results in an iron containing cobalt catalyst with a higher Cselectivity. In certain preferred embodiments the concentration of iron increases towards the surface of the resulting catalyst particles whereas the cobalt concentration is constant which further increases the selectivity of the catalyst to producing Chydrocarbons.

Fischer-Tropsch catalyst

The present invention relates to a process for the conversion of cobalt(II)hydroxide into cobalt(III)oxidehydroxide (CoOOH) by reaction of the cobalt(II)hydroxide with oxygen in the presence of certain metal compounds. The invention further relates to the use of cobalt(III)oxidehydroxide thus prepared in the preparation of catalysts or catalysts precursors, especially catalysts or catalyst precursors for the conversion of synthesis gas into normally liquid and normally solid hydrocarbons and to normally liquid or solid hydrocarbons, optionally after additional hydrotreatment, obtained in such a conversion process.

Catalytic process for the conversion of Co (II)hydroxide in Co (III)oxidehydroxide

The present invention relates to a catalyst for use in a process for the preparation of hydrocarbons comprising cobalt and manganese and/or vanadium, supported on a carrier, wherein the cobalt:(manganese+vanadium) atomic ratio is at least 12:1. Preferably, the cobalt:(manganese+vanadium) atomic ratio is at most 1500:1. The invention further relates to a process for the preparation of hydrocarbons which comprises contacting a mixture of hydrogen and carbon monoxide at elevated temperature and pressure with a catalyst as described hereinbefore. Typically, at least part of the cobalt is present in the metallic state.
