A composition for use after reductive activation as a catalyst for the conversion of synthesis gas to hydrocarbons having a carbon number greater than one, which composition has the formula:

Syngas conversion catalyst production and use thereof

Process for production of a syngas conversion catalyst

C.sub.1 to C.sub.4 oxygenated hydrocarbons are produced by contacting synthesis gas at a temperature in the range 150.degree. C. to 450.degree. C. and a pressure in the range of 1 to 700 bars with a catalyst comprising a supported mixture of a rhodium component and a silver component. The preferred support is silica. Other metal components which may be incorporated on the support are iron, manganese, molybdenum, tungsten, ruthenium, chromium, thorium and zirconium. Furthermore the support can be activated prior to incorporation of the metal components.

Process for the production of C.sub.1 to C.sub.4 oxygenated hydrocarbons

An oxygenated hydrocarbon product comprising methanol and ethanol is produced by hydrogenating carbon monoxide at a temperature in the range 150.degree. to 450.degree. C. and a pressure in the range 1 to 700 bars in the presence as catalyst of a supported mixture of the metals rhodium, silver, zirconium and molybdenum and optionally also one or more of the metals iron, manganese, rhenium, tungsten, ruthenium, chromium, thorium and potassium. The preferred support is silica.

Process for the production of oxygenated hydrocarbons by the catalytic

Oxygenated hydrocarbon compounds containing from one to four carbon atoms, e.g. acids, alcohols and/or aldehydes are produced by reacting carbon monoxide with hydrogen in the presence of a supported mixture of a rhodium component and a chromium component, optionally incorporating also iron, manganese, molybdenum, tungsten or ruthenium at elevated temperature and generally at elevated pressure. A preferred support is silica which may be activated by the addition of metal and non-metal activators followed by calcination, prior to incorporation of the rhodium and chromium components.
