FIELD: chemistry.
SUBSTANCE: invention relates to a process of production of hydrocarbons in a continuous mode starting from a synthesis gas in the presence of a catalyst, comprising a synthesis step in which the synthesis gas is reacted with a catalyst in a Fischer-Tropsch synthesis reactor (4). The process is characterized in that, simultaneously with the synthesis step, the following successive steps are carried out: a) charging the catalyst precursor containing cobalt oxide to a recovery reactor (2) for this purpose; b) reducing, in the reduction reactor, the catalyst precursor charged in step a) by contacting a reducing gas containing hydrogen (H2) And/or carbon monoxide (CO); c) feeding the catalyst reduced in step b) to the synthesis reactor (4). The introduction of the reduced catalyst into the synthesis reactor (4) is carried out via a feed line (9) of the reduced catalyst, connecting the reduction reactor (2) to the synthesis reactor (4).
EFFECT: use of the present invention makes it possible to reduce the frequency of reactor shutdowns and quickly go into operation after a stop, and to exclude the stage of protection of the freshly reduced catalyst.
