Activated CarbonActivated Carbon Plant


1. Activated carbon is a kind of carbon processed to have pores, in the form of black powder or granule, particle or honeycomb structure abnormally, also can be in ordered structure. It has highly developed pore structure, which makes it a super fine adsorption agent, due to its high degree of microporosity, just one gram of activated carbon has a surface area in equal size of eight tennis courts. And its adsorption power is effected both by physical and chemical characteristics, it is composed of not only carbon element, but also lesser content of Hydrogen, Helium, Oxygen and ash content as well, which as a result makes the formation of hexacyclic structure on carbon basis. Due to the hexacyclic structure, the formation of microporosity and large surface area are caused.
Activated carbon can be made from different carbon-contained materials, like wood, sawdust, coal, charcoal, peat, lignin, kernel, sugar cane pulp, bone, lignite, oil dreg, etc. Based on different materials, techniques and using areas, different activated carbons can be produced, in which activated carbon made from coconut shell is of best quality and been seen most frequently.

Activated carbon is widely used in industry, farming, family and environmental protection, including electricity, petrochemical, gold production, food, medicine, air filter and many other application, and there is going to be great prospect and large market.

The great events of using charcoal
⑴First being documented in Egypt for medical use in the year of B.C.1550
⑵Used by Greek physician Hippocrate in the year of B.C.460-359 for treating seizure
⑶ Documented and used by Chinese physician for medical use in 1518-1593
⑷ In 1793 being used for treating ulcer
⑸ In 1794 first being used by an England sugar factory for bleaching The great events of using activated carbon
6.Invented in 1900 and first used in industry
7.Gas purification(gas mask)---used in 1915 world war one
8、Water purification(deodorant)---in 1927 used for water deodorant, and widely used    later in 1940s
9、Gold production(gold-loaded carbon)---firstly being used in 1940s for gold cyanidation in China
10、Later stage---from 1950s to now, widely being used in environmental protection, medical care, food, filtering, car industry and family use

Basically there are two processes for making activated carbon, first process includes dewatering and carbonation, which means the raw material will be dried and dewatered at the temperature of 170-600 degrees Celsius and then the organic materials contained will be carbonated to 80% extent. The second process includes activation of charcoal, which is concluded by activation agent and steam with the reaction between charcoal, during the endothermic reaction combined gas of CO and H2 will be burned to heat the charcoal to 800-1000 degrees Celsius to burn out all the decomposables, so microporosity structure and large surface area are effected, hence with strong adsorption power.(The exact technique will be designed based on raw materials and different applications with different carbonation, activation, acid wash, crushing or grinding process.)
