DOWEX OPTIPORE™ Polymeric Adsorbents

DOWEX OPTIPORE™ Polymeric Adsorbents are designed to remove organics from aqueous streams or vapor in oil field applications or to decolorize high fructose corn syrup in sweetener operations. With an optimized pore structure to maximize loading, these polymeric adsorbents offer a cleaner alternative to activated carbon. The adsorbent can be desorbed/regenerated for reuse.


DOWEX OPTIPORE™ SD-2 Polymeric Adsorbent is specially designed for decolorization as well as taste and odor removal in sweetener applications. It has a high specific surface area and high porosity which shows exceptional mechanical, thermal and chemical stability. This adsorbent has similar pore size distribution and adsorption properties to activated carbon so that it can be used as a direct replacement for carbon in many sweeteners applications. DOWEX OPTIPORE SD-2 has the additional advantage of containing macropores which improve the bulk movement of solutions in and out of the bead. The resulting improvement in kinetics leads to faster production flow rates and smaller beds. The adsorbent is lightly functionalized with weak base groups to provide a hydrophilic character giving the adsorbent good wettability and compatibility with acid and base regenerants. Regeneration requires only dilute caustic, dilute acid, and hot water. DOWEX OPTIPORE SD-2 complies with the U. S. Food, Drug and Cosmetic Act as amended under Food Additive Regulation 21 CFR 173.25.
