The prepn. of a catalyst comprising a support, which is an oxide of Si, Al, Ti, Zr, Sn, Mg, or Ln ( Ln is a rare earth), and (as % relative to support) 1-60% of Co, 0.01-20% of an element A (Ru, Pt, Pd, or U), and 0.01-20% of an element B (Mo or W), comprises: (1) forming a precursor comprising the Co and part of the support; (2) partially reducing the precursor in the presence of a reducing agent; (3) depositing, on the reduced precursor, the remainder of the catalyst. Also claimed, is the use of the catalyst system in a 5 or more C hydrocarbon synthesis from synthesis gas. |
