Company Information

Ganzhou Green Top produces a full line of activated carbon (pellets, granular, & powder) based on wood, bamboo, coal and coconut shell with special emphasis on water treatment, food & beverage, chemical processing,  pollution control ect.

 

Product Description

Coconut Activated Carbon is with very large internal surface areas characterised by microporosity along with relatively high hardness and low dust make these carbons particularly attractive for water and critical air applications such as point of use water filters and respirators respectively. The activated carbon is extensively used in the refining and bleaching of vegetable oils and chemical solutions, water purification, recovery of solvents and other vapours, recovery of gold, in gas masks for protection against toxic gases, in filters for providing adequate protection against war gases/nuclear fall outs, etc.

 

Application of coconut shell activated carbon:

In gold recovery applications, adsorption forces remove gold from solutions and adhere the metal complex to the carbon surface. Because the reaction occurs at the surface of the carbon, the adsorption process is relatively easy to reverse, we call it '' desorption''. While it is important to maximize the adsorption of gold from the solution, it is equally as important to subsequently desorb the gold from the carbon. Any molecules that remain adsorbed after elution or stipping translate into gold that can't be recovered.

 

Coconut activated carbon is the precursor for gold recovery applications because of its tight pore structure, high activity and hardness.

Process (Steam Activation)

 

 

The process of activation is carried out in two stages. Firstly the coconut shell is converted into shell charcoal by carbonization process which is usually carried out in kilns. The coconut shell charcoal is activated by reaction with steam at a temperature of 900oC -1100oC under controlled atmosphere in a rotary kiln. The reaction between steam and charcoal takes place at the internal surface area, creating more sites for adsorption. The temperature factor, in the process of activation is very important. Below 900oC the reaction becomes too slow and is very uneconomical. Above 1100oC the reaction becomes diffusion controlled and therefore takes place on the outer surface of the charcoal resulting in loss of charcoal.
