About Us

Established in 2009 Pat Impex is a leading manufacturer, supplier and exporter of high quality Activated Carbon i.e., Activated Carbon Powder and Granular Activated Carbon. The company supplies Activated Carbon to various industries in India as well as global market.

Activated Carbon is a porus form of carbon which is manufactured from various carbonaceous raw materials like Pine wood, Coconut shell, Coal, Eucalyptus, Peat, Saw dust, Rice husk, Lignite etc. It is preapered through Carbonisation & Activation of Organic substance. During Carbonisation most of non-carbon elements, Hydrogen, Oxygen are first removed in Gaseous form & it develops the internal pores and then after it is Activated through Chemical Activation or Steam Activation.In Activation process, it increases the numbers & dimensions of Pores & hence it has large internal surface area.

Activated Carbons are the most powerful adsorbents known. It is basically a solid material consisting mainly of pure carbon. A characteristic feature is its porous structure and the resulting immense surface area which may be as large as 1500 m2/gm. Due to its exceptional adsorption qualities, activated carbon is widely used in process destined to purify, discolor, recuperate and remove odors at low cost and superior efficiency. Activated carbons work on the principle of adorption. Adsorption is an interfacial process involving the collection of gaseous or solute components on the surface of adsorbent solids. This phenomenon is associated with physical attractive forces that bind gaseous and solute molecules commonly known as Van-der-Waals forces. Adsorption is thus a physical process, i.e. the substances adsorbed on the solid do not undergo any chemical reaction with the latter. The adsorbing solid is referred to as adsorbent and the substance to be adsorbed from the liquid or the gas phase as the solute.


ACTIVATED CARBON

  • Pellets Activated Carbon
  • Granular Activated carbon
  • Powder Activated Carbon
  • Chemically Activated Carbon
  • Steam Activated carbon
  • Wash Activated carbon

Activated Carbon Pellets

This type of activated carbon is used for vapour phase applications mainly solvent recovery.It is also used for making activated carbon catalyst due to its large surface area and hardness.

Applications of Activated carbon Pellets:

  • Air stripper off gas
  • Its purifies carbon dioxide
  • Used to purity nitrogen in various plastics manufacturing process
  • Used as a catalyst support and protector
  • Used in gasoline vapour recovery
  • Used in recovery of various useful solvents which are emitted out as waste gases in various  industries
  • In gassifiers to purify the gases
  • To remove odors from the air and gases

GRANULAR ACTIVATED CARBON

Granular Activated carbon is produce from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of porous on the surface. The resulting big particles are then crushed and sieved to get the desired particle size. Our main grades of granular activated carbon are given below. We can customize the iodine value as well as particle size according to your requirements.

Applications of Granular Activated Carbon:

  • It is used in effluent treatment plant to reduce BOD/COD/Color from industrial water.
  • It removes chlorine and organic impurities from drinking water in the last stage filtration in our common house hold filters.
  • It is used as adsorbent of poisonous gases in gas masks for industrial as well as defense purpose.
  • To adsorb moisture from compressed air in paint shops
  • To dechlorinate waters in swimming pool and soft drink plant
  • To remove oil from hot condensate
  • Top quality granular activated carbons are used in the process of gold recovery in which the molten one is passed over a bed of activated carbon where the gold is adsorbed on the carbon and recovered.
  • Used to manufacture catalyst
  • Remove of dissolve organic impurities
  • Breweries and distilleries
  • Catalyst carrier in petroleum refineries

Activated Carbon Powder [Steam Activated Carbon]

Our Powder Activated carbon is Manufactured using pure pine wood which is an excellent base for manufacturing activated carbon with good adsorption power.

The steam activated carbon is done by activating in a rotary kiln by heating high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCL/H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as 50 ppm.

The gradation of different qualities of activated carbon is done on the basis of methylene blue value and iodine value.The Iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. we can relate the iodine value of activated carbon directly to its surface area because of the above fact. 

  • Washed Activated carbon
  • Unwashed Activated Carbon

Application of Steam Activated Carbon Powder

  • It is mainly used in the decolorisation of active pharmaceuticals ingredients
  • Decolorisation of plasticizers, drug intermediates, dyes & dye intermediates, food color, glycerin and fine chemicals
  • Used also as drug in capsules and tablet forms for stomach ailments and applications
  • Used to purify intravenous fluid & Injections
  • Used by the pesticides and insecticides industry for decolorisation

CHEMICALLY ACTIVATED CARBON

Applications of Chemically Activated carbon Powder:

  • It is used in decolorization of liquids having impurities with larger pore size i.e sugar solutions, glucose, dextrose,lactose & other starch sugar solution
  • Used in decolorization of vegetable oils and fats and herbal products
