【 摘 要 】

Mn-based catalysts were synthesized by a sol-gel method and implied to removal of HCN under low temperature and micro-oxygen conditions. The results show the catalysts that modified by manganese oxide have superior catalytic oxidation activity for HCN conversion. Furthermore, the introduction of barium can promote the selective catalytic oxidation of HCN to N2. The introduction of H2O apparently inhibited the conversion efficiency of HCN, and the H2O could restrain the production of N2yield at lower temperature but it nearly had no effect on N2yield at higher temperatures.
