    Charcoal is a dark brown or black porous solid fuel left over from incomplete combustion of wood or wood raw materials or pyrolysis in the absence of air.

    Coke is made from bituminous coal through the high-temperature coking process, which is mainly used for blast furnace ironmaking and blast furnace smelting of non-ferrous metals such as copper, lead, zinc, etc., and plays the role of reducing agent, heating agent and material column framework.

    Activated carbon is also known as activated carbon black. It is amorphous carbon in the form of black powder or granules. Technology: In addition to carbon, the main components of Shanghai Zhenghai activated carbon include oxygen, hydrogen and other elements.

    In terms of elemental composition, more than 80%-90% of activated carbon is composed of carbon, which is also the reason why activated carbon is a hydrophobic adsorbent. In addition to the I carbon element, the activated carbon also contains two types of admixtures: one is the chemically bound elements, mainly oxygen and hydrogen, these elements are left in the carbon due to incomplete carbonization, or in the activation process, the foreign non-carbon elements are chemically combined with the surface of the activated carbon.

    Carbon black is carbon black.

    1] (carbon black, also known as carbon black) is an amorphous carbon. Light, loose and very fine black powder, with a very large surface area ranging from 10 to 3000 m2 g, is the product of incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil, etc.) under the condition of insufficient air. Specific gravity made of natural gas is called "gas black", oil made of "lamp black", and acetylene made of acetylene is called "acetylene black".

    In addition, there are "groove black" and "furnace black". According to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black" and so on. It can be used as a black dye for the manufacture of Chinese ink, ink, paint, etc., and is also used as a reinforcing agent for rubber.

    Summary. Pro: Activated charcoal is not charcoal, it is two different things.

    Is activated charcoal charcoal.

    Pro: Activated charcoal is not charcoal, it is two different things.

    What is the difference between activated carbon and charcoal 1, the difference between the two, activated carbon is in addition to carbonization, but also after activation and drying and other treatments can be obtained, charcoal is the wood is not completely burned, and the residual solid fuel, only after carbonization treatment. 2. The composition of the two is different, activated carbon is mainly composed of carbon elements and foreign oxygen and hydrogen, charcoal composition is a combination of carbon, hydrogen, oxygen and nitrogen, charcoal and oxygen are completely burned to produce carbon dioxide, and incomplete combustion produces toxic carbon monoxide. 3. The use of the two is different, activated carbon has a large adsorption capacity for organic matter, and is often used for adsorption to remove indoor pollution, deodorization and automobile deodorization.

    Charcoal can be used as a fuel, and is often used as a raw material for carbon disulfide and activated carbon or other fuels in the chemical industry.

    The choice of activated carbon 1, look at the adsorption index of activated carbon, the higher the adsorption index, the higher the adsorption capacity of activated carbon, when buying activated carbon, you can make a decision according to the indicators provided by the manufacturer, and choose the activated carbon that suits you. 2. The more voids on the activated carbon, the smaller the density, the lighter the texture, the activated carbon can be thrown into the water, and a series of bubbles appear, the longer this situation lasts, the better the adsorption of the activated carbon. 3. Activated carbon has the ability to absorb colored liquids into light or colorless, and the stronger the decolorization effect of the item, the stronger the adsorption of activated carbon.

    Types of charcoal Charcoal is mainly divided into four categories: white charcoal, black charcoal, activated carbon and machine-made charcoal.

    Activated carbon is a kind of microcrystalline carbon material made of carbon-containing materials with a black appearance, developed internal pore structure, large specific surface area and strong adsorption capacity. It is a commonly used adsorbent, catalyst or catalyst carrier, which is widely used in almost all sectors of the national economy and people's daily life. Charcoal and charcoal are basically the same, but the structure of charcoal is tighter, so it is harder than charcoal, and charcoal and charcoal do not have the strong adsorption function of activated carbon because they have not undergone special treatment.

    Put the charcoal or bar charcoal pure and put it in the pipe, let the high-temperature water vapor blow the charcoal, and dredge the micro-void in the hidden charcoal, so that it is basically activated carbon.

    Hello, dear! Charcoal, coke, and activated carbon are all materials made up of the element carbon, and they all share certain similarities in structure to graphite. First of all, these materials are all made up of layered carbon atoms.

    The carbon atoms in graphite form a planar hexagonal network with three adjacent carbon atoms and a hole around each carbon atom. The carbon atoms in charcoal, coke and activated carbon are also arranged in a hexagonal network. Secondly, the carbon atoms in these materials are connected by covalent bonds, which are characterized by the sharing of electrons, which makes the distance between the carbon atoms shorter and the structure more stable.

    Finally, the structure between the carbon atoms in these materials all has a certain layered structure, which makes them have high electrical and thermal conductivity. In conclusion, although charcoal, coke, and activated carbon have different preparation processes and raw materials, their structures are similar to graphite, which is one of the reasons why they have similar substance-based stuffing and chemical properties.
