چکیده انگلیسی
Nickel catalysts supported on CeO2 were prepared and evaluated in aqueous-phase reforming of glycerol. Three different methodologies of synthesis were used: wet impregnation, co-precipitation and combustion, and the catalysts were characterized by chemical composition, textural analysis, crystalline structure and reducibility. The reaction was carried out in a batch reactor with solution of 1 and 10Â wt.% glycerol, at 523 and 543Â K. A maximum glycerol conversion of 30% was achieved by the catalyst prepared by combustion at 543Â K using solution 1% glycerol. In the gas phase, the molar fraction of H2 was always higher than 70% and formation of CH4 was very low (<Â 1%). The increase in glycerol concentration decreases the conversion and H2 formation.
