Production, characterization and evaluation of the adsorptive potential of activated carbon briquette shaped

ThisActivated carbons briquette shaped were prepared from Candeia wood waste, generated in the extraction of α-bisabolol oil process. The material was briquetted, carbonized and activated with CO₂, varying the temperature (700-900°C) and activation time (1-3 hours). The characterization of the activated carbons were performed by: elemental analysis (CHN-O), analysis of the functional groups (Boehm titration), Burn-off, estimated BET surface area, iodine index, calculation of surface area with methylene blue, adsorption tests with methylene blue (MB) and phenol and mechanical resistance (IRI).The results showed that increasing temperature and time of activation promoted an increased in the surface area, pore volume, basicity and adsorption capacity of AM and phenol.
