Title:
SUPPORTED CATALYST FOR PREPARING SUGAR ALCOHOLS BY MEANS OF THE CATALYTIC HYDROGENATION OF SUGAR, METHOD FOR PREPARING THE SUPPORTED CATALYST, AND METHOD FOR PREPARING SUGAR ALCOHOLS USING THE SUPPORTED CATALYST
Document Type and Number:
WIPO Patent Application WO/2012/141523
Kind Code:
A2
Abstract:
The present invention relates to a supported catalyst for preparing sugar alcohols by means of the catalytic hydrogenation of sugar, to a method for preparing the supported catalyst, and to a method for preparing sugar alcohols using the supported catalyst. More particularly, the present invention relates to a catalyst in which ruthenium or ruthenium boron is supported by a carrier alone or a carrier mixed with elements selected from silica, alumina and titania, a zeolite carrier, or a carrier alone or a carrier mixed with elements selected from silica, alumina, and titania coated with a material made of nickel metal oxides. The present invention also relates to a method for preparing such a catalyst, and to a method for preparing sugar alcohols at a high yield rate by hydrogenating sugar through the repeated use of a relatively smaller amount of said supported catalyst without regeneration. The supported catalyst of the present invention enables the preparation of highly pure sugar alcohols without causing the dissolution or inactivation of catalyst components during repeated use for hydrogenation, thus generating little by-products and waste. The supported catalyst of the present invention enables the preparation of sugar alcohols without a complicated separation process.
