Investigating Sustainable Hydrogen Production via Catalytic Steam Reforming of Ethanol over Stable Commercial Catalysts

Renewable ethanol serves as a compelling source for generating clean hydrogen. In this study, we conducted an in-depth exploration of the catalytic steam reforming of ethanol to produce hydrogen employing four commercial catalysts under optimized reaction conditions, including temperature, pressure, and the steam-to-ethanol ratio. Among the catalysts investigated, two nickel-based catalysts with different nickel contents a exhibited superior performance, displaying the highest hydrogen yield, ethanol conversion, and hydrogen selectivity. Notably, these nickel-based commercial catalysts achieved a hydrogen selectivity of 75%, a hydrogen yield of 89%, and an ethanol conversion rate of 100%.
