Study of the catalyst supported on the rice husk ash for NO reduction with carbon monoxide

Abstract

In our research, rice husk ash was used as the catalyst supporter of Fe/Cu oxides in the reduction of NO by CO. Rice husk ash contains abundant amorphous SiO2 and it would be a good catalyst supporter indicated by the characterization results. Different combustion conditions were tested to obtain the proper rice husk ash. Characterization methods were employed to study the physical properties. The results of the catalytic activity testing experiment were highly in accordance with the characterization results. Fe2Cu1 based on rice husk ash had approximately 100% conversion rates of both NO and CO, which indicated the superiority of the rice husk ash and Fe-Cu oxides. Moreover, O2 content, CO/NO ratio and SO2 had little influence on this new combination. This remarkable performance was due to the strong interaction between the rice husk ash and metal species. The results of our research will provide some instructions for the improvement of industrial denitrification.
