Three tons. Carbon black (also known as carbon black) is an amorphous carbon. Light, loose and extremely fine black powder with very large specific surface area ranging from10 to 3000m2/g is the product of incomplete combustion or thermal decomposition of organic matter (natural gas, heavy oil, fuel oil, etc.). ) in the case of insufficient air. According to relevant data, the carbon emission of producing one ton of carbon black is 3 tons. Carbon emission is the general name or abbreviation of greenhouse gas emission. The most important gas in greenhouse gases is carbon dioxide, so the word carbon is used as a representative.
