αFeOOH nanoparticles were prepared using homogeneous precipitation and ammonia titration methods The catalytic activity of the catalysts using αFeOOH nanoparticle as active ingredient for COS hydrolysis were tested by a microreactorchromatography assessing apparatus at the atmospheric pressure in the temperature range from25?℃~60?℃ with gas hourly space velocity 10?000?h-1 The performance of the catalysts for H2S removal was investigated by means of thermal gravimetric method The results show that the nanoparticlebased catalyst is highly active for COS hydrolysis at low temperature at high space velocity Conversion of COS can attain 100% by use of series Ⅰ and Ⅱ catalysts at 60?℃ and 40?℃~45?℃ respectively The highest saturated sulfur capacity for H2S can reach 2172% at 60?℃ Further, it is also observed that the surface energy distribution on the catalysts is heterogeneous and a compensation effect exists
