Title:
METHOD FOR PURIFYING SUCROSE SOLUTION AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/129698
Kind Code:
A1
Abstract:
　In the present invention, a sucrose solution is purified by passing the sucrose solution in order through a first column packed with an acrylic-based OH-type strong basic anion exchange resin and a second column arranged downstream from the first column and packed with a mixture of a styrene-based OH-type strong basic anion exchange resin and an H-type strong acidic cation exchange resin. Through this purification method, high desalination and decoloring performance are obtained, degradation of the styrene-based strong basic anion exchange resin of the second column can be suppressed, and the amount of regenerating solution used for the styrene-based strong basic anion exchange resin of the second column can be reduced.
