The invention relates to a process for the hydrogenation of sugars and sugar mixtures from the group consisting of isomaltulose, trehalulose, maltulose, leucrose and lactulose to sugar alcohols or sugar alcohol mixtures wherein the sugars or sugar mixtures are hydrogenated with hydrogen in an aqueous solution at elevated temperature and elevated pressure, using a nickel-containing catalyst attached to a carrier.

Process for the hydrogenation of sugars

The invention relates to a process for the hydrogenation of sugars and sugar mixtures to sugar alcohols or sugar alcohol mixtures wherein the sugars or sugar mixtures are hydrogenated with hydrogen in an aqueous solution at elevated temperature and elevated pressure by using a shell catalyst comprising a mixture of a pure Raney metal and a Raney metal alloy and wherein the shell catalyst has an essentially catalytically inactive core functioning as a carrier and a catalytically active shell.
