  • Patent number: 5932106
    Abstract: Process for regeneration of ion-exchange resins, used in sugar decolorization, using a sucrose solution with sodium or calcium chloride, or another chloride, namely potassium or a mixture of those chlorides, alkalinised with calcium hydroxide. The regeneration of the resin is made with a flow between 1 to 3 cubic meters of a regenerating solution by a cubic meter of resin/hour and a temperature between 40.degree. to 70.degree. centigrade. The sucrose solution used in this resin regeneration process contains between 30 to 600 g of sucrose per liter of solution; calcium hydroxide between 1 to 40 g of CaO per liter of solution; and calcium or sodium chloride, or another chloride, namely the one of potassium, or a mixture of these compounds, in such a quantity that chloride ion concentration is between 3 to 30 g per liter of solution. This regenerating solution is passed through the resin in a quantity between 2 to 4 cubic meters per cubic meter of resin.
