Activated carbon, also called activated charcoal, a form of graphite. The greater surface area brings the strongest adsorption forces and adsorbing porosity. In the adsorption process, activated carbon is used for adsorption of organic compounds, increasing the function group numbers and molecular weight.
Many of raw materials were used for the preparation of activated carbon. Coal, coconut shells and waste sawdust are the main resources. Fujian exports the highest volume of wood based activated carbon in China.
In 2016, China exports totally 17k tons wood based activated carbon, at 16% CAGE, values 62 millions dollars. Fujian at 40% of market shares.
FOREVEREST® Wood Based Activated Carbons are produced by the waste sawdust from logging, building and processing. The preparation of phosphoric acid activation process is more eco friendly than ZnCl2.
WFA is wood based activated carbon used for sugar decolorization process. It also can be used for refining process of saccharin, glucose, xylitol.
WAA is a type of wood based activated carbon that produced by phosphoric acid activation process. It is specialty used for amino acid adsorption in water treatment, food industry and treatment process.
WWT is a form of wood based activated carbon used for water treatment. It is produced by chemical activation of sawdust using unique phosphoric process.
