Process for preparing a catalyst containing an active phase based on a group VIII metal and a porous support, comprising the following steps:

Process for preparing a fischer-tropsch catalyst in the presence of an additive and of a specific calcining step

The invention relates to a catalyst containing an active cobalt phase, deposited on a support comprising alumina, silica or silica-alumina, said support also containing a mixed oxide phase containing cobalt and/or nickel, said catalyst having been prepared by introducing at least one hydrocarbon organic compound of formula CH. The invention also relates to the use thereof in the field of Fischer-Tropsch synthesis processes.

Cobalt catalyst comprising a support containing a mixed oxide phase including cobalt and/or nickel produced using a hydrocarbon compound

A catalyst containing an active phase comprising at least one metal of group VIIIB selected from cobalt, nickel, ruthenium and iron deposited on a support containing silica, alumina and at least one simple spinel MAl2O4 or mixed spinel MxM'(1-x)Al2O4) which is or is not partial, wherein M and M&#x2032; are separate metals selected from the group formed by magnesium, copper, cobalt, nickel, tin, zinc, lithium, calcium, caesium, sodium, potassium, iron and manganese, and wherein x is between 0 and 1, the values 0 and 1 being themselves excluded, characterised in that said active phase further comprises boron, the boron content being between 0.001% and 0.5% by weight with respect to the total weight of the catalyst, the value 0.5 being itself excluded.
