Abstract

A process for preparing a catalyst support or a supported metal catalyst which process comprises: (a) admixing a refractory oxide having a surface area of at least 0.5 m²/g with a solution of a precursor of the refractory oxide and, if a supported metal catalyst is prepared, with a precursor of the metal or the metal itself, yielding a slurry, (b) drying of the slurry, and (c) calcining. Further, a catalyst support or a supported metal catalyst which is obtainable by the said process; the use of the said supported metal catalyst in a three phase chemical process; and a process for producing hydrocarbons, which process comprises contacting a mixture of carbon monoxide and hydrogen at elevated temperature and pressure with the said supported metal catalyst wherein the said supported metal catalyst comprises a Group VIII metal at least partly in metallic form.

Claims

1. A process for preparing a catalyst support or a supported metal catalyst which process comprises:

(a) admixing a refractory oxide having a surface area of at least 0.5 m²/g with a solution of a precursor of the refractory oxide and, if a supported metal catalyst is prepared, with a precursor of the metal or the metal itself, yielding a slurry,

(b) drying of the slurry, and

(c) calcining.

2. A process as claimed in claim 1, characterised in that the precursor of the refractory oxide is an organic salt or complex compound.

3. A process as claimed in claim 1 or 2, characterised in that the refractory oxide comprises titania and the precursor of the refractory oxide is a precursor of titanium dioxide.

4. A process as claimed in any of claims 1-3, characterised in that the quantity of the precursor of the refractory oxide is in the range of from 0.5 to 25% w, preferably from 1 to 10% w, calculated as the weight of the refractory oxide which can be formed from the precursor, relative to the weight of the refractory oxide employed in step (a).

5. A process as claimed in any of claims 1-4, characterised in that the solvent is an aqueous solvent.

6. A process for producing a supported metal catalyst, characterised in that a precursor of the metal or the metal itself is deposited on a catalyst support which is prepared according to a process as claimed in any of claims 1-5.

7. A catalyst support or a supported metal catalyst which is obtainable by a process as claimed in any one of claims 1-6.

8. A supported metal catalyst as claimed in claim 7, characterised in that the catalytically active metal is a Group VIII metal, preferably cobalt.

9. A supported metal catalyst as claimed in claim 7 or 8, characterised in that the Group VIII metal is present at least partly in metallic form.

10. A process for producing hydrocarbons, which process comprises contacting a mixture of carbon monoxide and hydrogen at elevated temperature and pressure with a supported metal catalyst as claimed in claim 9, preferably in a three phase chemical process.
