ABSTRACT:
A method for purification of polyhydric alcohols such as sugar syrup by removing chromophoric components, trace metals, and other impurities comprising preparing a liquid slurry mixture of filter particles, including an anion exchange resin, a cation exchange resin, and a filter aid material, the anion and cation exchange resins being smaller than about 100 mesh (about 150 microns); precoating a porous support means with the slurry mixture; and passing the polyhydric alcohol through the precoat layer and the porous support means to purify the alcohol. A further embodiment includes the step of regenerating the precoat layer by delivering a brine solution having a pH between 7 and 10 through the precoat layer.
