Process for synthesizing C5+ hydrocarbons in the presence of a catalyst prepared using at least one cyclic oligosaccharide

A process for synthesizing essentially linear, saturated C5+hydrocarbons, consisting of bringing a feed comprising synthesis gas into contact with at least one catalyst the active phase of which comprises at least one metal from group VIII deposited on a support formed by at least one oxide, said catalyst being prepared using a process comprising at least:

• i) at least one step for bringing at least said support into contact with at least one solution containing at least one precursor of said metal from group VIII;
• ii) at least one step for bringing at least said support into contact with at least one organic compound formed from at least one cyclic oligosaccharide composed of at least 6 α-(1,4)-bonded glucopyranose subunits;
• iii) at least one calcining step to obtain at least said metal from group VIII in the oxide form;
• the steps i) and ii) possibly being carried out separately, in any order, or simultaneously.
