Three common questions about using activated carbon

1.Can activated carbon spontaneously combust?

Activated carbon generally does not spontaneously combust because it reacts chemically with certain substances at room temperature. Its unique internal porous structure provides space for micro-particles to exist, which to some extent reduces its reactivity. Moreover, activated carbon needs to reach its own ignition point to burn; the ignition point of carbon materials is generally around 300 degrees Celsius, while the ignition point of granular activated carbon is approximately 170 degrees Celsius.

2.Can activated charcoal be sun-dried?

Activated carbon can be dried in the sun, but it is not advisable to reuse it by exposing it to direct sunlight. This is because the harmful substances adsorbed by activated carbon are difficult to desorb. It requires manufacturers with activated carbon regeneration qualifications to use specific equipment and special processes, such as thermal regeneration, chemical elution, solvent extraction regeneration, and biological regeneration, to complete the process. The performance of activated carbon cannot be restored by simply drying it in the sun.

3.What are the main components of activated carbon?

Activated carbon is composed of 80%-90% carbon. In addition to carbon, it also contains two types of admixtures: one is chemically bonded elements, mainly hydrogen and oxygen, and the other is ash (impurities), which is the inorganic part of activated carbon and usually contains a small amount of adsorbed water.
