Abstract

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.
