Lignite and Wood Activated Carbon
Lignite and Wood activated carbon types are two unique products used in various applications. Wood based activated carbon is produced from various sources of wood via chemical activation. Wood based carbons have a unique pore structure with a high surface area ideal for decolorization applications. We also deal with powder activated carbon. Contact us for more detail.
Lignite activated carbon is produced via steam activation of lignite coal material. This product is used in various applications such as potable water and surface water treatment. Lignite carbon has a lower pore volume compared to other carbons but works effectively in select applications.
Karbonous Inc is the one and the only name that comes to mind when thinking about wood-based lignite activated carbon since we are renowned powder activated carbon suppliers in the market. Leading manufacturing plants and industries in California work with us on a large scale. Industrialists find high-quality and bulk activated and reactivated wooden carbon with us that provides cost-effective solutions.
Here are some of its properties that make it suitable for the applications, such as:
- Decolorizing the fruit juices, food stuff, beverages, and pharmaceutical products
- Solvent recovery
- Purification of sweeteners, edible oils, starches, etc
- Vehicle Evaporative Loss Control Devices
- Methylene Blue adsorption;
- Methylene Blue adsorption; it indicates the absorption capacity of medium sized molecules, for instance, in dyes. Methylebe blue absorption is pretty higher for carbons which have mesopores (2-5 nm diameter) in the majority.
- Molasses index;
- Molasses index; the molasses adsorption from solution gives an indication of the large molecule absorption capability. However, the absorption in this case is also strongly dependent on the structure of the mesopore.
In various applications, the purity factor and the chemistry of the surface play important roles in determining carbon quality. On the contrary, wood carbons usually have better purity compared to coal based. It can also be improved by washing, and similarly, the pH can also be changed according to the requirement.
Lignite and Wood Activated Carbon Products at Karbonous
Lignite is a soft and dark brown coal with a distinct wood-like texture. Its density is not too high and neither too low, and the composition of carbon within the lignite is between bituminous coal activated carbon and peat coal.
If you want to know how to make activated charcoal from wood, here are the quick steps:
- Burn the wood in a large metal pot
- Leave it for a while until it gets cool to room temperature
- Wash the charcoal you get from the metal pot
- After the charcoal is dry, you will need to grind it into a fine powder
- Add a solution of water and calcium chloride
- Finally, cook this mixture
Activated carbon from lignite is also used for mobile water treatment systems. It can be used for water treatment because the capacity of adsorption of Lignite activated carbon makes it perfect for eliminating or removing a range of contaminants from liquids, air, water, and gases.
We manufacture and supply the granular activated carbon by using steam activation of lignite coal. In particular, this blend is manufactured for a rapid adsorption rate in percolation columns. Precisely, 12×40 Lignite Based Activated Carbon is considered to be the most efficient among the other general purpose granular carbon grades for the applications, such as purification of food and fine chemicals.

What are the characteristics and properties of lignite?
Lignite is brownish-black in color and has a carbon content of 60-70 percent dry ash-free. However, compared to bituminous coal, its inherent moisture level can reach up to 75%, and its ash content ranges from 6–19%. As a result, on an as-received basis, its carbon content is often just 25-35 percent (i.e., comprising both natural moisture and mineral matter).
Is activated carbon made from Wood?
Yes, activated carbon is made from wood, among other sources, such as made from bituminous coal, coconut shell, lignite coal, and wood.
What is wood based activated carbon?
Wood-based activated carbon is made from specific types of wood and sawdust. This type of carbon is made by activating it with steam or phosphoric acid. The bulk of pores in wood-based carbon are in the meso and macropore region, which is ideal for decolorizing fluids, such as water.
What are the common applications of lignite based activated carbon?
- In the mobile water treatment system
- Food purification system
- Production of fine chemicals
- And much more.
