First Claim
1. A hydrogenolysis system comprising:
- a reactant reservoir configured to contain a polyhydric alcohol compound; and
a reactor coupled to the reactant reservoir, the reactor housing an Ru-comprising hydrogenolysis catalyst and configured to expose the polyhydric alcohol compound to the catalyst, wherein the contents of the reactor is maintained at a neutral or acidic pH during the exposing.

Abstract
Hydrogenolysis systems are provided that can include a reactor housing an Ru-comprising hydrogenolysis catalyst and wherein the contents of the reactor is maintained at a neutral or acidic pH. Reactant reservoirs within the system can include a polyhydric alcohol compound and a base, wherein a weight ratio of the base to the compound is less than 0.05. Systems also include the product reservoir comprising a hydrogenolyzed polyhydric alcohol compound and salts of organic acids, and wherein the moles of base are substantially equivalent to the moles of salts or organic acids. Processes are provided that can include an Ru-comprising catalyst within a mixture having a neutral or acidic pH. A weight ratio of the base to the compound can be between 0.01 and 0.05 during exposing.
