2045664 9008592 PCTABS00001 A reduced supported Group VIII metal catalyst of enhanced activity is obtained by an ante-pre-reduction treatment in which a supported Group VIII metal catalyst precursor is soaked in a reducing atmosphere at temperatures below a pre-reduction temperature (typically about 140·C) at which appreciable pre-reduction of the catalyst can be detected. This catalyst may be, for example, a ruthenium on alumina catalyst and is characterised by a Group VIII metal surface area of at least about 45 m2/g of Group VIII metal present in the catalyst, as measured by adsorption of carbon monoxide thereon.
