Bimetallic cobalt-containing catalysts supported on alumina have been studied in the Fischer-Tropsch synthesis. It has been shown that a promotion of Co/Al2O3 by iridium leads to dispergation of both metals. It was supposed that the metal dispergation occurred due to M-M interaction with formation of the bimetallic nano-particles of cluster type. These particles have the high catalytic activity, selectivity and stability in the Fischer-Tropsch synthesis. It was observed that by regulation of the process conditions it is possible to obtain the definite hydrocarbon fractions. Thus, the increase both CO+H2 ratio and space velocity is accompanied by high olefin yield.
