Claims
- 1. In a Fischer-Tropsch synthesis process for making hydrocarbons which comprises reacting hydrogen and carbon monoxide in the presence of a catalyst having a first component of ruthenium supported on a second component which is a high surface area catalyst support, the improvement comprising the presence in the catalyst of a third and promoting component of bromine moieties and of the first component being in the form of metallic ruthenium.
- 2. A process according to claim 1, carried out at a temperature of 150.degree. to 300.degree. C.
- 3. A process according to claim 1, carried out at a temperature of 180.degree. to 250.degree. C.
- 4. A process according to claim 1, wherein the second component is alumina.
- 5. A process according to claim 1, wherein the second component is gamma-alumina.
- 6. A process according to claim 5, wherein the gamma-alumina has a surface area of from 50 to 350 m.sup.2 g.sup.-1.
- 7. A process according to claim 5, wherein the gamma-alumina has a surface area of from 150 to 300 m.sup.2 g.sup.-1.
- 8. A process according to claim 1, wherein the ruthenium is present in an amount of 0.05 to 5% by weight of the total catalyst.
- 9. A process according to claim 8, wherein the ruthenium is present in an amount of 0.1 to 2% by weight of the total catalyst.
- 10. A process according to claim 8, wherein the ruthenium is present in an amount of 0.1 to 1% by weight of the total catalyst.
- 11. A process according to claim 1, wherein the atomic ratio of bromine to ruthenium is from 0.1 to 6:1.
- 12. A process according to claim 11, wherein the atomic ratio of bromine to ruthenium is from 1.5 to 4:1.
