  Impact of inherent calcium in coal on the structure and …

  20231120 · Coal with a high content of calcium could result in a low yield of AC. Calcite could transform into calcium oxide. During AC preparation by flue gas activation, calcium oxide also could react with CO 2 and transform into calcium carbonate. Calcite in coal reduced the degree of AC's graphitization.
