A series of Mn/TiWOx catalysts were prepared and used in NH3-SCR reaction for NOx emission control. The experimental results showed that the SCR activities of Mn/TiWOx catalysts are higher than that of Mn/TiO2 catalyst. After that, several characterization techniques including XRD, H2-TPR, NH3-TPD, XPS were used to investigate the effect of TiWOx support on the SCR performance of Mn/TiWOx (1:1) catalyst...
The effect of HF treatment on the performance of ceria for selective catalytic reduction of NO with NH3 was investigated in this study. The experimental results showed that HF treatment could greatly enhance the SCR performance of ceria within the temperature range of 100–400°C. From the characterization results of Brunauer–Emmett–Teller (BET), X-ray diffraction (XRD), temperature programmed reduction...
Thermochemical conversion of crops straw is receiving renewed attention, due to the energy and material recovery that can be achieved. However, it still lacks the kinetic background which is of great importance for a successful design of thermochemical process. In this work, pyrolysis test for soybean straw was performed in a non-isothermal thermogravimetric analysis (TGA) in order to determine the...
