Redispersal of Ru, Os, Rh and Pd catalysts and processing therewith
This patent describes a process for redispersing and reducing a supported metal catalyst. Wherein the catalyst metal is ruthenium, osmium, rhodium or palladium supported by a refractory support and wherein the catalyst had been prepared by impregnating a metal salt of the catalyst metal on the refractory support and activated by passing hydrogen gas over the catalyst at a temperature of between about 150{degrees} C. and 350{degrees}C. for a period of time sufficient to reduce the metal salt on the refractory support; the supported metal catalyst had been deactivated in a vapor phase process for the preparation of an {alpha}-substituted acrylate ester; and the above-mentioned deactivated catalyst is redispersed and reduced.
