摘要

The process of bleaching liquor of sugar with a final stage of filtration to remove suspended particles.The process of bleaching liquor of sugar, with a final stage of filtration, comprising a step of discoloration by passage of the original liquor, possibly associated with an oxidizer (e.g. hydrogen peroxide) by a resin adsorbent and / or an anionic resin of T. IPO strongly basic,With these resins regenerated by an alkaline solution of ethanol containing peroxido hydrogen and / or a solution of calcium saccharate containing a chloride salt, and optionally by a system which uses activated carbon granules, regenerated chemically.Preferably the resin adsorbent is composed of a matrix of polystyrene divinyl benzene resin and anionic type strong base is composed of a polystyrene divinyl benzene matrix containing quaternary ammonium groups linked to chloride ions.The effluent of the regenerations, containing sucrose and / or ethanol, are sent to a unit of production of alcohol, separately or as a mixture with molasses, syrup or syrup.
