[ We claim:] [1.] A process for the synthesis of essentially linear and saturated hydrocarbons containing at least 25% by weight of C.sub.5.sup.+ hydrocarbons with respect to the total amount of hydrocarbons formed, from a synthesis gas CO--(CO.sub.2)--H.sub.2, in the presence of a catalyst, in which the synthesis gas is converted to hydrocarbons at a total pressure which is in the range 0.1 to 15 MPa, a temperature which is in the range 150.degree. C. to 350.degree. C., an hourly space velocity which is in the range 100 to 20000 volumes of synthesis gas per volume of catalyst per hour, and an H.sub.2 /CO molar ratio in the synthesis gas in the range 1:2 to 5:1, said catalyst comprising (a) a support formed of at least one oxide of an element selected from the group consisting of: Si, Al, Ti, Zr, Sn, Zn, Mg or Ln (wherein Ln is a rare earth); (b) cobalt; (c) titanium; and (d) at least one additional element A selected from the group consisting of copper, ruthenium, platinum, palladium, scandium and yttrium, said catalyst having been produced by at least the following successive steps:(1) forming a precursor comprising cobalt, element A and the support;(2) at least partial reduction of said precursor in the presence of at least one reducing compound; and(3) depositing titanium on the reduced precursor.
