Hydrogenation of carbon monoxide was studied at 523 K under 1.0 MPa over SiO2-supported bimetallic catalysts. The activities of SiO2-supported bimetallic catalysts of FeCo, CoNi and NiFe for CO hydrogenation were greater than those of monometal catalysts. The product distribution was shifted to the higher hydrocarbons by alloying of metals. The SiO2-supported bimetallic catalysts were slightly less active than TiO2-supported ones; the product distribution was not affected by the support. Olefins, paraffins and gasoline compounds were produced selectively on FeCo, NiFe and CoNi bimetallic catalysts, respectively. The cobalt-nickel system is particularly suitable for catalytic gasoline synthesis because this catalyst is most selective for formation of higher hydrocarbons as well as most active for CO conversion. It is clear that alloying affects the adsorption ability of hydrogen and carbon monoxide, resulting in a change in the ratio of activated hydrogen and carbon monoxide on the surface.
