Abstract
Samples of activated carbon loaded with different amounts of phenol from aqueous solutions were regenerated in an atmosphere of argon at a constant rate of increase in temperature of 7.6 K min-1. Heating to 385°C caused a 49% loss in phenol, after which the rate of decomposition decreased markedly. A residue of 32.6% of the phenol originally adsorbed, remained on the carbon at temperatures higher than 800°C. The amount of residue left by the decomposition reactions showed a linear dependence on the initial amount of phenol loaded. A two-stage first order thermal cracking model was applied successfully to the decomposition of phenol loaded on activated carbon. © 1986.
