Preparation of High Surface Area Activated Carbons from Tobacco Stems with K2CO3
Activation Using Microwave Radiation.
With increased amount of K2CO3
added, the weight loss of cellulose in the lower temperature zone (200-315 [degrees]C) increased greatly and the activation energies of hemicellulose and cellulose pyrolysis decreased notably from 204 to 42 kJ/mol.
