Syngas with a H2/CO mol.ratio between 0.75 and 1.75 is converted into hydrocarbons by contacting it first with a special cobalt-containing Fischer-Tropsch catalyst under such conditions that the conversion lies within a specified range depending on the H2/CO mol.ratio of the syngas feed, and thereafter, after water removal, with a catalyst composition comprising both hydrocarbon synthesis- and CO-shift activity. A high H2 + CO-conversion combined with a high C5+ selectivity can be obtained starting from a syngas with a H2/CO mol.ratio (F) between 0.75 and 1.75 by carrying out the process in two stages as described hereinbefore under such conditions that in the first stage the following relation is met: in which C represents the H2 + CO-conversion in mol.%
