Macroporous Weakly Basic
Anion-exchange Specialty Catalyst


KP-3013 is a premium grade catalyst with a form of macroporous styrene-based weakly alkaline anion-exchange resin, synthesized by special advanced technology. For its particles are with complete bead integrity and highly-solid structure, this resin performs excellent resistance to mechanical and osmotic shock as well as against organic pollution.

Attributed to its efficient properties of strong adsorption or exchange capacity of weak-basic anions with strong-acid radicals of organic macromolecules including metal complexes within mineral liquids during its regeneration, KP-3013 model, as a role of catalyst, is widely used in the demineralization system and applied in sugar refining & de-colorization to prevent strong-basic anions from being polluted by organics to the greatest extent, and induce and accelerate all the replacement reactions on top of all.
