A series of Mn-Ce based materials were synthesized by co-precipitation method and were examined for mercury removal at lower temperatures (50–250°C) in the absence of HCl. The effect of preparation conditions (metal oxides and calcination temperature) and reaction conditions (reaction temperature and gas constituents) was investigated. Results showed that Mn0.1Ce0.2Al-400 was found to be the most...
A series of Ce modified TiO2 supported Co-Mn catalysts (CoxMn5/TiCey) prepared by sol-gel method and impregnation method were evaluated for simultaneous catalytic oxidation of Hg0 and NO in the simulated flue gas. Results showed that the catalysts exhibited good capacity of simultaneous catalytic oxidation of Hg0 (around 70%) and NO (around 40%) at 300°C using a simulated flue gas (Hg0, NO, SO2, O...
To achieve the high Hg0 oxidation efficiency in the atmospheres with low concentration of HCl or in temporary absence of HCl and facilitate the following SCR process, CuCl2-CoOX/Ti-Ce catalyst for simultaneous catalytic oxidation of Hg0 and NO in a pre-sco process (300–420°C) was developed. N2 adsorption-desorption, XRD, TG and XPS techniques were used to characterize the catalyst and its catalytic...
The Co–Mn/Ti–Ce catalyst prepared by sol–gel and impregnation method was evaluated for catalytic oxidation of Hg0 in the simulated flue gas compared with Co/TiO2 and Co–Mn/TiO2. The results showed that Co–Mn/Ti–Ce catalyst exhibited higher catalytic activity (around 93% Hg0 removal efficiency in the temperature of 150 °C with 6% O2, 400 ppm NO, 200 ppm SO2 and 3% H2O) than Co/TiO2 and Co–Mn/TiO2....
