Differences in carbonization of coconut shell charcoal materials in different regions　

There are different raw materials for different product types of activated carbon, which can be made from a variety of raw materials such as coal, coconut shell and wood, etc. The management of the production and development process of activated carbon can be categorized into high-temperature chemical process and high-temperature thermal process. At present, the raw materials of coconut shell activated carbon produced by domestic activated carbon manufacturers mainly come from Southeast Asia. The main products are Hainan, Vietnam, the Philippines, Indonesia, Thailand and so on.

Comparison of these coconut shell carbonization is as follows.

Vietnam carbonized material.

Disadvantages:High moisture and volatile content, fixed carbon content of about 50%, finished carbon of about 30%. Quality and index are not stable. Advantages:Thicker coconut shell, relatively low price.

Philippine Carbonized Material.

Disadvantages:Thin coconut shells, not very large, high price, Advantages:Better control of moisture and volatiles, and fewer impurities, in addition to closer transportation distance. However, due to the scarcity of resources, it is difficult to form a supply scale.

Indonesian Charcoal.

Disadvantages:High price. Advantages:Carbonized crushing technology is mature, the carbonized material produced has thick and strong carbon walls, moisture and volatile content is well controlled, and the fixed carbon content can be more than 73% (73-76%). But the domestic price is relatively high, because the tariff of the origin is higher than others, plus the freight cost is also higher.　

Hainan development of local for carbonization material:.

Hainan has few resources of coconut shell. The carbonization process is also primitive, so the indicators of carbonized materials vary greatly. A small amount of well controlled fixed carbon content can reach more than 65%, but most of them can only reach about 60%. Due to the short growing period of Hainan coconut shell, the volatile substances and water content of Hainan coconut shell are high, and the carbonization strength is low.

Therefore, coconut shell activated carbon manufacturers can choose raw materials through different origins according to the student's own product development conditions and geospatial location, from import channels, quality, freight and other aspects need to be considered.
