Iron catalysts for Fischer-Tropsch synthesis, activated by alkaline additives are active in the synthesis of hydrocarbons from CO and H/sub 2/. It is well known that catalysts obtained by applying K/sub 2/(Fe/sub 3/(CO)/sub 11/) complexes on ..gamma..-Al/sub 2/O/sub 3/ have increased selectivity in the formation of lower olefins from CO and H/sub 2/. IR spectroscopy using catalysts based on K/sub 2/(Fe/sub 3/(CO)/sub 11/) showed that during heat treatment in vacuum, CO, H/sub 2/, CO + H/sub 2/ atmosphere a transition is observed of polynuclear complexes found on a carrier surface, to a (Fe(CO)/sub 5/, Fe(acac)/sub 3/ and Fe(C/sub 5/H/sub 5/)/sub 2/, in Fischer-Tropsch synthesis. A study was made in this paper of the effect of the type of initial Fe-complex: iron pentacarbonyl Fe(CO)/sub 5/-I, iron acetylacetonate Fe(acac)/sub 3/-II, ferrocene Fe(C/sub 5/H/sub 5/)/sub 2/-III, on the activity and selectivity of Fe-K catalysts in the synthesis of lower olefins from CO and H/sub 2/. In these complexes Fe is oxidized from Fe/sup 0/ to Fe/sup 3 +/ (3). In order to prepare catalysts by the same method, Fe(acac)/sub 3/ was selected as Fe/sup 3 +/ compound, which is soluble in alkaline methanol solution.
