The results indicate that increasing metal loadings promotes the phenol oxidation activity of the CuO/AC catalyst-sorbent,and enhances the affinity between the phenol and the CuO/AC catalyst-sorbent.This makes the adsorbed phenol desorb and/or de-associatively desorb from the catalyst-sorbent difficult.In addition,the ignition activity of the CuO/AC catalyst-sorbent itself is improved with increasing metal loadings.According to these results,it is clear that there is a proper metal loadings range of 3 ~ 5% for the CuO/AC catalyst-sorbent used for catalytic dry oxidation of phenol,which is calculated as the Cu weight percent. %K metal loadings %K CuO/AC catalyst-sorbent %K catalytic dry oxidation %K phenol
