摘要:
A highly efficient catalyst Rh/CeO2/SiO2 for cellulose gasification at low temperature (773-873 K) in a continuous feeding fluidized bed reactor has been developed. The Rh/CeO2 catalyst also exhibited the activity. However, this catalyst deactivated because of sintering of CeO2 under reaction conditions. The sintering of CeO2 was prohibited by loading of CeO2 on high surface area SiO2. The amount of char deposition in the order of Rh/CeO2/SiO2 < Rh/CeO2 < G-91, which can be explained by the oxidation activity measured by TGA of cellulose mixed with catalyst.
