TLDR
In this paper, a supported ruthenium catalyst which has been used for conversion of carbohydrates to polyhydric alcohols is regenerated by contacting the catalyst with an aqueous solution of a mineral acid, such as sulfuric, hydrochloric, or phosphoric acid.Abstract:
Regeneration of supported ruthenium catalysts. A supported ruthenium catalyst which has been used for conversion of carbohydrates to polyhydric alcohols is regenerated by contacting the catalyst with an aqueous solution of a mineral acid, such as sulfuric, hydrochloric, or phosphoric acid. Dilute acids, e.g., 0.01 N to 0.5 N, are preferred.read more

Method for hydrogenating aqueous solutions of carbohydrates
TL;DR: The use of zinc on titanium dioxide in the hydrogenation of glucose affords sorbitol in excellent yields with quite high selectivity as discussed by the authors, which may be used advantageously in the reduction of aqueous solutions of carbohydrates.

Sulfide-modified ruthenium catalyst
Michael Dubeck,Gordon G. Knapp +1 more
TL;DR: In this article, a process for the production of a lower polyhydric alcohol or a mixture thereof by the hydrogenation and hydrolysis of a carbohydrate is described, where the first stage hydrogenation produces higher polyhydrics alcohols, such as sorbitol.

Process for producing maltitol
Sugimoto K,M Mitsuhashi,M Hirao +2 more
TL;DR: In this paper, a process for producing maltitol from a starch slurry is described, which consists of hydrolyzing the mixture with beta-amylase and alpha-1,6-glucosidase to produce a high maltose containing product and catalytically hydrogenating the maltose with Raney nickel after adjusting the pH of the product with calcium carbonate.
Patent
Manufacture of xylitol
TL;DR: In this paper, a process for producing xylitol from lignin-free hemicellulose materials was proposed, wherein the polysaccharides have been converted to monosaccharides, subjecting said materials to fermentation with a hexose fermenting yeast and thereafter hydrogenating aqueous medium.
