Abstract
A commercial activated carbon was oxidized with nitric acid to tailor the structure of pore and adjust the distribution of surface functional groups. The textual properties of catalysts was characterized using N2adsorption, and Boehm titration was applied to quantitative analysis of the functional groups on activated carbon surface. The catalytic activity of modified activated carbon was performed by trickle bed at specific temperature and pressure. The oxidized activated carbon displayed lower removal rate for phenol. This phenomenon was reasonably interpreted by small specific surface area and increase in oxygen-containing surface functional groups. The catalytic activity test showed that higher reaction temperature and higher oxygen partial pressure were favorable for phenol conversion.
