| 概要 |
This study aimed to investigate the e ect of carbon derived from glucose (C) on the physicochemical characteristics and catalytic activity of Ni, supported over SiO2, ZSM-5, and TiO2 in methane dry re...forming. Among the Ni catalysts without C, Ni/SiO2 exhibited the highest CH4-CO2 conversion and stability at all experimented temperatures. On the other hand, the C-incorporated catalysts prepared by glucose impregnation, followed by pyrolysis, showed dissimilar performances. C improved the stability of Ni/SiO2 in the reforming at 650 C and 750 C and increased the CH4 and CO2 conversion to the level close to the thermodynamic equilibrium at 850 C. However, this element did not substantially a ect the activity of Ni/ZSM-5 and exerted a retarding e ect on Ni/TiO2. Characterizations with H2-TPD, XRD, EXAFS, and STEM-EDS revealed that the di erent influences of C by the supports were attributed to the extent of metal dispersion and metal-support interaction.続きを見る
