Abstract
The invention concerns the preparation of a catalyst comprising a support comprising at least one oxide of the element Si, Al, Ti, Zr, Sn, Zn, Mg or Ln (where Ln is a rare earth), cobalt, titanium, at least one element A selected from the group formed by copper, ruthenium, platinum, palladium, scandium and yttrium, and characterized in that it comprises at least the following successive steps: PA1 (1) forming a precursor comprising at least cobalt, element A and the support; PA1 (2) at least partial reduction of said precursor in the presence of at least one reducing compound; and PA1 (3) depositing titanium on the reduced precursor. The invention also concerns the catalyst which can be produced using this process and the use of the catalyst in a process for synthesizing C.sub.5.sup.+ hydrocarbons from synthesis gas.
