Characterizations of bimetallic NiV-supported SiO2 catalysts prepared for effectively hydrogen evolutions from ethanol steam reforming |
| 초록 |
Bimetallic NiV supported on SiO2 catalysts were tested in the steam reforming of ethanol. The catalysts were prepared using a wet impregnation method, and all the catalysts had a Ni oxide or NiV oxide loading of 30 wt. % vs. the SiO2 weight. The catalysts were characterized by XPS, nitrogen adsorption/desorption isotherm, XRD, TPD with CO and H2O, and TPR with H2. XRD and XPS revealed the crystallite sizes and oxidation states of the NiO or metallic Ni in NiV/SiO2 catalysts, respectively, which indicated suppressed agglomeration between the Ni particles by the V promoters. The ESR catalytic tests for hydrogen production were performed in a fixed bed reactor containing 0.4 g of catalyst at 650 oC and a 6,000 h-1 GHSV after the H2-pretreatment with an inlet H2O:EtOH ratio of 3:1. These tests showed that hydrogen evolution on the Ni8V2/SiO2 catalyst during ESR was improved by suppressing the deposition of carbon compared to those on the Ni/SiO2 catalyst. |
