Abstract:
A process for producing sugar-alcohol comprisingmelting a mixture of nickel and aluminum to form a melted mixture, quenching droplets of said melted mixture of nickel and aluminum to form a quenched lump alloy having a grain diameter of 1 to 15 mm, breaking said quenched lump alloy into particles, selecting said particles having a grain diameter of 2 to 4 mm, activating the selected particles of said quenched lump alloy to form a fixed bed Raney catalyst, hydrogenating sugars under hydrogen pressure with the fixed bed Raney catalyst, crushing said fixed bed Raney catalyst to form a powder Raney catalyst, activating the powder Raney catalyst, and hydrogenating sugars under hydrogen pressure with the powder Raney catalyst.
