In this work, a series of coal-based active carbon (CAC) catalysts loaded by Al2O3 were prepared by sol-gel method and used for the simultaneous catalytic hydrolysis of carbonyl sulfide (COS) and carbon disulfide (CS2) at relatively low temperatures of 30–70 °C. The influences of calcinations temperatures and operation conditions such as: reaction temperature, O2 concentration, gas hourly space velocity (GHSV) and relative humidity (RH) were also discussed respectively. The results showed that catalysts with 5.0 wt% Al2O3 calcined at 300 °C had superior activity for the simultaneous catalytic hydrolysis of COS and CS2. When the reaction temperature was above 50 °C, catalytic hydrolysis activity of COS could be enhanced but that of CS2 was inhibited. Too high RH could make the catalytic hydrolysis activities of COS and CS2 decrease. A small amount of O2 introduction could enhance the simultaneous catalytic hydrolysis activities of COS and CS2.
Graphical AbstractAl2O3-K/CAC catalyst demonstrated high activity and economical efficiency. The influences of calcinations temperatures and operation conditions such as: reaction temperature, O2 concentration, gas hourly space velocity (GHSV) and relative humidity (RH) were also discussed respectively.Figure optionsDownload as PowerPoint slide
