Catalytic pyrolysis of rice husks for syngas production over Fe-based catalyst in a fixed-bed reactor

摘要

Rice husk (RH) was pyrolyzed in a fixed-bed reactor between 400 and 800 degrees C with Fe-based catalysts and the outlet gases were analyzed online by gas chromatography. The results showed that Fe2O3 has a good catalytic activity in the pyrolysis. The influence of Fe2O3 catalyst was to convert RH to largely syngas. The concentration of H-2 increased with increasing temperature and could be released completely at 700 degrees C with the addition of Fe2O3. The concentration of CH4 was not affected, indicating that Fe2O3 had no effect on the methanation.
