Activated Carbon for Colour Removal

Decolourising charcoal refers to finely manufactured activated charcoal that is generally used to reduce the colour of the solution. Small particles of decolourising carbon provide a large surface area that allows effective adsorption of large colour molecules.

Decolourisation of Sugar

Sugar products are made from raw materials usually derived from cassava and converted into a monosaccharide solution by enzymes and water electrolysis. Some factories use hydrochloric acid and water electrolysis to produce monosaccharide solutions. The yellow pigment produced by the hydrochloric acid method is darker than the latent HMF pigment produced by the enzymatic method. Therefore, activated carbon can remove impurities such as HMF and Fe as well as discolouration. Carbontech activated carbon is an ideal option to effectively remove such impurities.

Sugar Beet Products

For the decolourisation of sucrose, customers can opt for the exclusive activated carbon from Carbontech. This activated carbon is made from low-ash and low-sulphur coal and uses advanced grinding and reforming briquetting technology. The activated carbon is widely used in the sugar refinery and can be customised to contain a highly efficient and stable magnesium oxide.

Citric Acid Colour Removal

Citric acid is a type of organic acid and the pigments it contains are usually red and yellow in colour. Carbontech activated carbon is able to effectively remove pigments and dyes in citric acid.

Glycerine Cleaning

Palm oil contains glycerine, a diesel by-product obtained during the production of biodiesel. Carbontech activated carbon can effectively remove oil and macromolecular pigments that cannot be removed during glycerine purification.

Carbontech activated carbon, specially formulated to meet the various requirements of these specific applications, offers a reliable and effective solution for colour removal processes.
