摘　　要：A series of coal-based active carbon(AC) catalysts loaded by Fe-Cu,Fe-Cu-Ce and Fe-Cu-La were prepared by the sol-gel method for carbon disulfide(CS2) hydrolysis and their performances for CS2 hydrolysis in a fixed-bed reactor were investigated in this work.The results showed that the kind of rare earth oxide and its content had obvious effect on hydrolysis removal of CS2.The effects of temperature,space velocity,CS2 concentration and O2 concentration were also discussed respectively.Furthermore,the suitable operating conditions were obtained.It was found that the poisoning of hydrolysis active sites could result in the formation of sulfuric acid on the catalyst surface.A series of coal-based active carbon(AC) catalysts loaded by Fe-Cu,Fe-Cu-Ce and Fe-Cu-La were prepared by the sol-gel method for carbon disulfide(CS2) hydrolysis and their performances for CS2 hydrolysis in a fixed-bed reactor were investigated in this work.The results showed that the kind of rare earth oxide and its content had obvious effect on hydrolysis removal of CS2.The effects of temperature,space velocity,CS2 concentration and O2 concentration were also discussed respectively.Furthermore,the suitable operating conditions were obtained.It was found that the poisoning of hydrolysis active sites could result in the formation of sulfuric acid on the catalyst surface.
