Claims
- 1. In a Fischer-Tropsch synthesis catalyst having a first component of ruthenium supported on a second component which is a high surface area catalyst support of gamma-alumina the improvement comprising the use of a third and promoting component of bromine moieties and of the first component being in the form of metallic ruthenium.
- 2. A catalyst according to claim 1, wherein the gamma-alumina has a surface area of from 50 to 350 m.sup.2 g.sup.-1.
- 3. A catalyst according to claim 1, wherein the gamma-alumina has a surface area of from 150 to 300 m.sup.2 g.sup.-1.
- 4. A catalyst according to claim 1, wherein the ruthenium is present in an amount of 0.05 to 5% by weight of the total catalyst.
- 5. A catalyst according to claim 4, wherein the ruthenium is present in an amount of 0.1 to 2% by weight of the total catalyst.
- 6. A catalyst according to claim 4, wherein the ruthenium is present in an amount of 0.1 to 1% by weight of the total catalyst.
- 7. A catalyst according to claim 1, wherein the atomic ratio of bromine to ruthenium is from 0.1 to 6:1.
- 8. A catalyst according to claim 7, wherein the atomic ratio of bromine to ruthenium is from 1.5 to 4:1.
- 9. A process for the production of a catalyst according to claim 1, comprising impregnating the support component with sources of ruthenium and bromine moieties, and thereafter converting at least a major proportion of the ruthenium present to the metallic form.
