ABSTRACT OF THE DISCLOSURE A catalyst composition for use in the production of hydrocarbons from synthesis gas comprises the essential metals (a) ruthenium and at least one of iron, cobalt and nickel, and (b) at least one of lithium, sodium, potassium, calcium and magnesium supported on silicalite, as described and claimed in United States Patent No. 4,061,724, the metals [(a)+(b)] being present on the silicalite support in an amount in the range from 0.5 to 15% by weight. The catalyst composition may be modified by addition of the hydrogen form of a crystalline zeolite having the composition expressed as mole ratios of oxides: 0.9 ? 0.2 M2/nO:W2O3:20 to 50 YO2:zH2O wherein M is at least one cation, n is the valence thereof, W is aluminium and/or gallium, Y is silicon and/or germanium and z has a value of 0 to 40, said zeolite being characterized by an XRD pattern which is substantially that of an MFI-type zeolite. Synthesis gas is converted to olefinic hydrocarbons using the un- modified catalyst and to gasoline range hydrocarbons using the modified catalyst.
