(A) Activated carbon, ACTIVATED NATURAL MINERAL PRODUCTS Carbon and mineral substances are called activated if their surface structure is modified by appropriate treatment (heat, chemicals and other m) to make them suitable for certain purposes, such as discoloration, absorption of gas or moisture, catalysis, ion exchange or filtration. These products are divided into two groups: (I) Products, the main characteristic of which is a very large specific surface area (about hundreds of square meters per gram) and the presence of van der Waals bonds (physical adsorption) or free chemical bonds that can be saturated with organic and inorganic molecules (chemical adsorption). These products are obtained by chemical or thermal treatment of certain plant or mineral substances (clay, bauxite, etc.) in the presence of natural impurities or additives of foreign substances. This treatment changes the structure of the basic substance, which is accompanied by an increase in the specific surface, and in the case of crystalline substances - deformation of the lattice due to the introduction or replacement of atoms with different valence. Valencies, thus remaining free, can interact with protons of silt and electrons on the surface, making these substances active as chemical adsorbents, catalysts or ion exchangers. (II) Products whose main characteristic is a relatively small specific surface area (of the order of 1 to 100 m2/g). Notwithstanding the fact that these products have a high density of electric charge, they do not have a noticeable adsorption capacity and therefore cannot be discoloring agents. On the other hand, these products in an aqueous suspension exhibit strong electrostatic interaction with colloids, facilitating or suppressing their coagulation, and are therefore suitable for use as filtering agents. Products of this type are also obtained mainly by heat treatment. The presence of alkaline substances in the calcification process sometimes contributes to the formation of surface charges.

This heading covers: (a) Activated carbon. It is usually obtained by treating vegetable, mineral or other carbon (charcoal, carbon from coconut peel, peat, lignite, coal, anthracite, etc.) at high temperatures in an atmosphere of water vapor, carbon dioxide or other gases (gas activation) or by calcination in a dry atmosphere of cellulosic materials impregnated with solutions of certain chemicals (chemical activation). Activated charcoal is used as a fine powder to discolor liquids in many industries (sugar or glucose production, oil or wine, medicines, etc.). In the form of grains, it is used to adsorb vapors (for example, to regenerate volatile solvents in dry chemical cleaning, to remove benzene from coal gas), to purify water or air, as a protective agent against toxic gases, in catalysis, or to remove the ivy of accumulated gas in the subelectrode layer during electrolysis (depolarization). (b) Other activated natural mineral products, such as (1) Activated diatomite. It consists of kieselguhr or some other silica fossils, from which calcium is removed by acids if necessary; the mass is calcified in contact with sintering substances such as sodium chloride or sodium carbonate, and then crushed and sorted by appropriate methods. However, diatomite calcined without sintering additives is not included in this heading (heading 2512). (2) Some volcanic minerals, such as perlite, which, after grinding, are subjected to a “heat shock” in a very hot flame (1000 °C or higher), are then re-molded and sorted. Activated perlite has the appearance of a very light shiny powder. Microscopic examination shows that it consists of very thin transparent flakes with an irregular surface. Both types of products mentioned in paragraphs (1) and (2) above have a very low apparent specific gravity and are filtering agents used mainly in the manufacture of chemical and pharmaceutical products (especially antibiotics), in the production of sugar or glucose, beverages, for water filtration, etc. (3) Activated clays and activated earths. This type of products includes some types of colloidal clays or clay lands activated according to their purpose with acid or alkali, and then dried and crushed. Activated with alkali, they are emulsifiers, suspension and agglomerating agents; they are, in particular, used for the manufacture of polishing and cleaning agents and, due to their ability to swell, to improve the properties of the molding mixture and drill paste. Once activated with acid, they are used mainly to discolor animal, vegetable or mineral oils, fats or waxes. (4) Activated bauxite. Bauxite is usually activated by alkali or appropriate heat treatment. It is mainly used as a catalyst, drying or discoloring agent. This heading also excludes: (a) mineral products having natural activity (e.g. fuller earth) which have not undergone any treatment capable of altering their surface structure (Chapter 25);

(b) activated chemical products, such as activated alumina (heading 2818), activated silica gel (heading 2811 or 3824), artificial zeolite having ion-exchange properties (heading 2842 or, if containing a binder, heading 3824) and sulphonated coal ion-exchangers (heading 3824); (c) activated carbon having the character of medicaments (heading 3003 or 3004) or put up in packings for retail sale as deodorisers for refrigerators, vehicles, etc. (heading 3307); (d) catalysts consisting of a chemical substance (e.g., a metal oxide) deposited on an activated support (e.g., activated carbon or diatomite) (heading 3815); (e) expanded perlite in the form of light spherical granules (heading 6806).

(B) Animal charcoal, Including Used Animal charcoal This category of goods includes a variety of charcoal obtained by carbonation of animal materials, in particular: (1) Bone charcoal obtained by calcination of low-fat bones in an autoclave. It is a porous black product with a low content of pure carbon (about 10 – 20% by weight, if not treated with acid, after treatment with acid, the carbon content increases significantly). Produced in the form of powder, grains, paste or pieces in the form of bones or parts thereof used to make it. Bone charcoal is a discoloring substance and is widely used in many industries, especially in the sugar industry, and is also used as a black pigment, for example, in the production of polishing agents and certain types of ink. Used bone charcoal is used as a fertilizer, as well as for the production of black pigments. (2) Blood charcoal obtained by calcination of dried blood in an autoclave. It is mainly used as a discoloring agent. (3) Ivory coal from ivory waste calcination. This product, which is usually finely ground black powder with a purple hue or small irregularly shaped cones, is used for artistic paints. (The term ivory coal is sometimes used to refer to certain types of bone charcoal.) (4) Skin charcoal, horn charcoal, hoof charcoal, turtle shell charcoal, etc.
