    Abstract: Chemical production processes are provided that include exposing a reactant composition to a catalyst composition to form a product composition, with the reactant composition including a multihydric alcohol compound and the catalyst composition being effective to dehydrate at least a portion of the multihydric alcohol compound. Embodiments of the process provide that the reactant composition is exposed to the catalyst composition for less than about 0.25 seconds and/or that the catalyst is maintained at a temperature of from about 2800C to about 3200C. Processes utilizing a reactant composition including a multihydric alcohol compound and an inert compound are also provided.

    Abstract: 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.
