Abstract
The invention relates to a continuous process for the preparation of a high-purity hydrogenated ose by catalytic hydrogenation of the corresponding ose in falling film reactors, wherein the hydrogenation is carried out in a series of fixed beds of ruthenium catalyst comprising: a) a first hydrogenation zone consisting of at least one fixed bed of ruthenium catalyst, and b) a second hydrogenation zone consisting of at least one fixed bed of ruthenium catalyst containing a promoter.

A continuous process for the preparation of a high-purity hydrogenated ose by hydrogenation of the corresponding ose in falling film reactors, comprising performing the hydrogenation in a series of fixed beds of ruthenium catalyst comprising:
- a) a first hydrogenation zone consisting of at least one fixed bed of ruthenium catalyst, and
- b) a second hydrogenation zone consisting of at least one fixed bed of ruthenium catalyst containing a promoter.
The process of claim, wherein the hydrogenated ose is sorbitol with a purity of at least 98.5% by expressed as dry weight of obtained hydrogenated ose based on the total weight of hydrogenated, ose non-hydrogenated ose and co-products.
