Abstract
A catalyst composition for use in the production of hydrocarbons from synthesis gas comprises the essential metals PA1 (a) at least one of iron, cobalt, nickel and ruthenium, and PA1 (b) at least one of lithium, sodium, potassium, calcium and magnesium supported on silicate, as described and claimed in U.S. Pat. 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: EQU 0.9.+-.0.2 M.sub.2 /.sub.n O:W.sub.2 O.sub.3 :20 to 50 YO.sub.2 :zH.sub.2 O wherein M is at least one cation, n is the valence thereof, W is aluminum 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 unmodified catalyst and to gasoline range hydrocarbons using the modified catalyst.
