ISOMERIZATION OF SUGARS

摘要

Disclosed are processes for isomerizing saccharides. Also disclosed are processes for converting saccharides to furan derivatives. Also disclosed are processes for converting starch to furan derivatives. The isomerization is performed in aqueous medium with a high-silica zeolite containing a metal known to have Lewis acid activity incorporated into the framework of the zeolite, the zeolite being Beta, CIT-1, ZSM-12, SSZ-33, SSZ-26, CIT-5 or high silica FAU type zeolite.
