Abstract

Deactivated waste activated carbon due to the deposition of boron in the exhaust gas from an incinerator was regenerated by the treatment with surfactant, HCl, and NH₃. The catalysts were characterized using BET surface area, ICP, XPS and FT-IR spectra. Sequential treatment with surfactant and HCl removed the adsorbed boron very effectively. NH₃ treatment increased the number of functional nitrogen groups in regenerated sample. For NH₃ selective catalytic reduction (SCR) of NO, sequential treatments with surfactant, HCl, and NH₃ showed the highest DeNOx activity, attributed to the increased metal removal efficiency, specific surface area and amount of nitrogen functional groups on the surface.
