    摘要: Hydrogenolysis processes are provided that can include providing a hydrogenolysis reactor having a catalyst therein. The catalyst can be exposed to a reducing agent in the absence of polyhydric alcohol compound while maintaining a temperature of the catalyst above 290° C. Hydrogenolysis processes can also include providing a passivated catalyst to within a reactor and exposing the catalyst to a reducing atmosphere while maintaining the catalyst at a temperature less than 210° C.Hydrogenolysis catalyst preparation methods are provided that can include exposing the catalyst to a first reducing atmosphere while maintaining the catalyst at a first temperature to reduce at least a portion of the catalyst. The method can also include passivating at least the portion of the catalyst and depassivating the portion of the catalyst in the presence of a second reducing atmosphere while maintaining the portion of the catalyst at a second temperature less than the first temperature.
