        Describes method for producing liquid hydrocarbons and oxygenated organic compounds with catalyst of the Fe type, fluidized catalyst of small particle size (2-200m), and for conditioning synthesis catalyst.  The synthesis gas, that contains H2, 62 and CO2 33%, is mixed with diluent gas H2 20, CO 1, CO2 35%, and the rest CH4) and charged into 1 of the 2 reactors (I). The H2: CO: CO2 ratio of the synthesis-gas stream should be 2-6: 1: 1-3.  The gasiform effluent is introduced into a product recovery system.  The residual gas, that leaves the product recovery system, is not introduced for the conditioning of the fresh catalyst in the other reactor (II).  The catalyst is ready to go onstream with the total synthesis gas charge as soon as the catalyst activity in reactor (I) is inactive.  At this point, another batch of fresh catalyst starts to be conditioned in reactor (II).
