General description

Activated carbon (AC) is a three dimensional highly microporous structure with high surface area. AC can be prepared from various carbon precursors, such as lignite, peat, wood, coal etc. AC powder is popularly used in adsorption or at catalyst support. The adsorption capability of activated carbon is determined by its pore size distribution, purity and degree of carbonization, surface chemistry. Method of activation also influences the final properties of the product. Activated carbon prepared from lignite are hard textured with small micropore volume and high pore size distribution.4 It is used as a carrier for catalysts and possess good filtering properties.

Application

Activated carbons may be used in:
  • Separating gas mixtures, such as; hydrogen-hydrocarbons,
  • Gas drying;
  • Selective gas adsorption
  • Gas storage
Activated charcoal Norit may be used in recovery of lithium for recycling lithium- ion batteries. It may be used to study the adsorption isotherm of 2,4,6-trichlorophenol (TCP). 6 Activated carbon may be used for ultrapurification of water, such as removal of anti-anxiety drug diazepam (valium) from spiked wastewater.
