Abstract:
Catalytic activity and coke reduction of Ni catalysts for ethanol steam reforming (ESR) can be enhanced by urea addition and support modification using partial doping of Gd into CeO2 framework and Ce into Al2O3 framework. Urea addition as a promoter enhances Ni dispersion from the self-explosion of NH4NO3 that formed during the catalyst preparation resulting in the increase of the catalyst activity for ESR. Ni catalyst over GDC, CeO2 framework partially doped with Gd2O3, was investigated for activity and coke formation in the laboratory and pilot scale. Ni/GDC exhibits the highest activity (2314 μmol/min) and the lowest coke formation (2.6 mg/gcat) at 700 °C compared to all of the prepared catalysts in the laboratory. The catalyst was molded and further investigated in 291 L pilot scale reactor at 800 °C which can produce H2 at the average rate of 20.40 L/min in continuous mode. Another support modification by partial doping of Ce into Al2O3 coupled with magnetic inducement was also developed and used as supports for Ni catalyst for ESR. This study discovered that the magnetic inducement with different pole arrangements applied during support preparation affect Ce composition and distribution in the Al2O3 framework. Ni/Ce-Al2O3 under magnetic inducement with the same pole arrangement exhibits the highest H2 production (2400 μmol/min) and lowest coke formation (2.8 mg/gcat) at all temperatures used in this study. The result shows that the combination of urea addition and using Ce-doped Al2O3 prepared under magnetic inducement as supports can provide a low cost modification for active Ni catalyst at low temperature with low coke formation
