Decreasing of activity of the denitration catalyst caused by arsenic adsorption is one of the big problems against the stable long term operation of the coal power plant. In order to remove arsenic from the catalyst by conversion of As2O5 to volatile As2O3, methanol was used as the carbon source for the reduction. Effects of treatment temperature, reaction time and partial pressure of methanol on changes in the removal extent of arsenic, the chemical forms of vanadium and the denitration activity were investigated.
