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.

Coconut Activated Carbin 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:

Steam activation and chemical activation are the two commonly used processes for the manufacture of activated carbon. However coconut shell based activated carbon units are adopting the steam activation process to produce good quality activated carbon. But to reduce the ash content, the aid washing is necessory after steam processing.

The specification of coconut shell granular activated carbon:

The particle size of wood activated carbon can be customized.

OEM is acceptable.

Sample is free for you. 

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 900^oC -1100^oC 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 900^oC the reaction becomes too slow and is very uneconomical. Above 1100^oC the reaction becomes diffusion controlled and therefore takes place on the outer surface of the charcoal resulting in loss of charcoal.
