A Spent (waste) granular or pelletized or Powder activated carbon can be recycled by thermal reactivation, in which the spent carbon is processed through a high temperature reactivation furnace at or above 850°C. The adsorbed organics on the carbon are thermally decomposed. The resulting gases are fed through an afterburner and a treatment system to allow emission to atmosphere in accordance with most stringent environmental regulations. Recycling by thermal reactivation is an environmentally responsible disposal method that helps to reduce CO2 emissions over the activated carbon and contributes to a sustainable use of the world's resources.

A If it is not already apparent, activated carbon purifies our world. It makes water drinkable; the air breathable and food stuffs edible. It ensures we have the best healthcare, and that we can enjoy the freedoms, and technological advances of the modern world. With Xingyuan, we can all create a Pure World, just as we have been doing since 1990.

A Activated carbon is commercially manufactured from coal, wood, fruit stones (mainly coconut but also walnut, peach) and derivatives of other processes (gas raffinates). Of these coal, wood and coconut are the most widely available. The product is manufactured by a thermal process, but in the case of raw materials such as wood, a promoter (such as an acid) is also used to develop the required porosity. Downstream processes crush, screen, wash and/or grind the multitude of products to the client's requirements.

A How an activated carbon is used depends very much on the application duty, and its form. For example, powdered activated carbon (PAC) is used to treat drinking water, by simply adding the required amount directly to the water and then separating the resulting coagulation matter (as well as other solids) before sending the treated water to the network. The contact with the organics present results in adsorption of them and the purification of the water. Granular carbons (or extruded pellets) are used in fixed filter beds, with the air, gas or liquid passing through it with a determined residence (or contact) time. During this contact the unwanted organics are removed and the treated effluent is purified.

A There are hundreds of different applications for activated carbon ranging from odour control of cat litter to the preparation of the most modern pharmaceuticals. Around the home, activated carbon may be present in domestic appliances; will most likely have treated the municipal water supply, purified the soft drinks in the refrigerator, and been used in the production of chemicals, in turn used to manufacture electronics, furniture and construction materials. And more; our waste is burned to generate electricity, the gases from which are purified by activated carbon. Odour control again at sewage processing facilities, uses activated carbon, and the reclamation of precious metals from mining spoils is big business.

A Activated carbon can be manufactured commercially in granular, pelletised and powdered forms. Different sizes are defined for different applications. For example, in air or gas treatment, the restriction to flow is import, and so coarse particles are used to minimise pressure loss. In liquid treatment, where the removal process is slower, then finer particles are used to improve the rate, or kinetics, of the purification process.

A Activated carbon works by a process of adsorption. This is an attraction of a molecule to the carbon's vast internal surface by weak forces, known as London forces. The molecule is held in place and cannot be removed, unless the process conditions change, for example heating or pressure. This can be useful as an activated carbon can be used to concentrate material on its surface, that can be later stripped and recovered. The use of activated carbon for gold recovery is one common example of this. In some cases, the activated carbon is chemically treated to remove pollutants and in this case the resulting reacted compound is generally not recovered. Activated carbon surface is also not completely inert, and a variety of catalytic processes can be achieved using and taking advantage of the extended internal surface area available.

A Activated carbon is a carbonaceous, highly porous adsorptive medium that has a complex structure composed primarily of carbon atoms. The networks of pores in activated carbons are channels created within a rigid skeleton of disordered layers of carbon atoms, linked together by chemical bonds, stacked unevenly, creating a highly porous structure of nooks, crannies, cracks and crevices between the carbon layers. Activated carbons are manufactured from coconut shell, peat, hard and soft wood, lignite coal, bituminous coal, olive pits and various carbonaceous specialty materials. Chemical activation or High Temperature Steam Activation mechanisms are used in the production of activated carbons from these raw materials. The intrinsic pore network in the lattice structure of activated carbons allows the removal of impurities from gaseous and liquid media through a mechanism referred to as adsorption. This is the key to the performance of activated carbon.
