Activated carbon: Types & Usesby Sanjeev Yadav SEO
Activated carbon or activated charcoal is known as the special appearance of carbon. When there is a need to increase the surface area through a chemical reaction or absorption, activated carbon is used. It creates low volume and tiny pores by processing the carbon.
Activated charcoal has a popular use as a biochar, which is usually extracted from charcoal. When the extraction comes from coal or corn, it becomes activated coal.
Activated carbon has the property of complex degree of micro-porosity. It means when there is any occurrence of gas absorption in the circumstances only 1 gram active carbon can create >32000 ft. surface area. It is also famous for its absorption properties.
Types of activated carbon:
Activated carbon manufacturer companies in Gujarat produce it in three different forms, which are extruded, granular, and powder. Each of these categories is available in multiple sizes. Users can choose the desired version of activated carbon-based upon their requirements and the demand of the applications.
Extruded carbon –
These cylindrical pellets of activated carbon have a diameter between 1 to 5 mm ranges. The raw materials used in the extrusion process make sure that the final product becomes efficient and strong enough for any kinds of heavy-duty applications. In the market, automotive emission control, gas purification, solvent recovery, etc. which application demands higher stock resistance, minimum pressure drop, and solvent recovery, extruded carbon is used.
Granular activated carbon –
The granular form is counted as the irregular shapes of carbon particles prepared by sieving and milling techniques. Size of granules varies between 0.2 – 5.0 mm. Granular particles have certain advantages over the powdered form in strength and durability. Granular activated carbon is harder and more durable, clean, and can be reused as many times as required. It is used to purify a huge volume of liquid or gas to a certain consistency.
Powdered activated carbon –
The powdered form of the activated carbons has a specific range of size distribution and limit remains in between 5 and 150 Å. Finer or coarser grades of powdered activated carbon are also available. This type of activated carbon has minimal processing costs and offers flexible operations. According to the demand of the application, its dosage can be increased or decreased. It is mainly used for liquid-phase absorption.
Uses of activated carbon:
The activated carbon manufacturers in Gujarat provide high-quality products to various industries to serve multiple purposes including –
• Metal extraction
• Air purification
• Methane and hydrogen storage
• Air filters
• Water purification
• Gold purification
• Teeth whitening
• Gas masks
• Sewage treatment, etc.
Application areas of activated carbon:
1. Industrial – It is mainly used in the metal finishing works for purifying electroplating solutions.
2. Medical – It can treat the poising effects of arsenic, alkali, methanol, ethanol, iron, lithium, and ethylene glycol, and oral ingestion overdoses.
3. Analytical chemistry – As per the activated carbon suppliers in Gujarat, it is used in the low-pressure partitioning of mono and di-trisaccharides carbohydrates and in the manufacturing of analytical protocols.
4. Environmental – Due to its absorption quality, it is vastly used in removing water pollutants.
5. Agricultural – It is the number one choice in the making of wines and production of livestock.
Activated carbon has several other useful applications in different industries.
