摘要

Abstract

The renewable hydrogen generation through ethanol steam reforming is one of the anticipated areas for sustainable hydrogen generation. To elucidate the role of Ni and Co with ZSM-5 support

catalysts were prepared by wet impregnation method and ethanol steam reforming (ESR) was performed. The catalysts were characterized by HR-XRD

ATR-FTIR

HR-SEM

TEM with SAED

EDAX

surface area analyzer and TPR. It had shown complete ethanol conversion at 773 K

but the selectivity in hydrogen generation was found higher for 10% Ni/ZSM-5 catalyst as compared to 10% Co/ZSM-5. The 10% Ni/ZSM-5 catalyst has about 72% hydrogen selectivity at temperature 873 K. It indicates that Ni is a more sustainable catalyst as compared to Co with ZSM-5 support for ESR. The C

was found major undesirable products up to 823 K temperature. Nevertheless

the 10% Ni/ZSM-5 catalyst had shown its stability for high temperature (873 K) ESR performance.
