Coal powder activated carbon and wood powder activated carbon
1 Material difference
Coal activated carbon from anthracite, containing from less to more number of aromatic rings, the structure is also more and more dense and orderly, especially the degree of high quality anthracite, structure of order is greatly increased, the ordered structure is close to three degrees space.
The main components of wood raw material is cellulose, hemicellulose and lignin, and more oxygen structure, such as cellulose molecules in the repeat unit containing the equivalent of 5 water molecules H and O, not far from the graphite structure, even the basic structure of graphite structure of aromatic ring has not been formed.
2 Moisture absorption capacity difference
Two kinds of powder activated carbon in the same humidity of space within a few days, and then said to take the same quality of the two kinds of carbon, small size is the coal, the volume is large wood charcoal.
3 Difference between combustion ash
The same quality of the two kinds of powder activated carbon combustion, less ash can be initially confirmed that the wood powder activated carbon.
4 Performance differences
Compared with wood powder activated carbon, coal powder activated carbon pores more uniform, higher hardness, better wear resistance, generally speaking, the life of wood powder charcoal is 1.4 times of the coal powder charcoal.
5 Use difference
Wood: suitable for glucose, sucrose, maltose, sugar refining, such as sugar, as well as citric acid, fat ammonia acid, oil, chemical products in the removal of large molecules, purification and refining.
Coal quality: suitable for food, medicine, decolorization, crystallization, filtration, purification and other fields. It is also the main material of activated carbon filter felt, activated carbon foam.
