Abstract

Glycerol hydrogen production by aqueous phase reforming (APR) has been shown to be an efficient method of treating glycerol, which is an abundant by-product of biodiesel production. This study investigates the APR of glycerol using a Pt/NiAl₂O₄ catalyst, aiming to develop a sustainable method for hydrogen production from biodiesel byproducts. In comparison with traditional supports, NiAl₂O₄ provides improved thermal stability and resistance to phase transformation. Characterization techniques have revealed that the NiAl₂O₄ support enhances the dispersion and stability of Pt particles, contributing to a glycerol conversion into gaseous products of 99.9% and a lifespan of longer than 530 hours (only 2% loss). Reaction pathways were explored, suggesting that Pt/NiAl₂O₄ effectively promotes both dehydrogenation and water-gas shift reactions, thereby highlighting its potential for APR applications in bio-hydrogen production.

在 Pt/NiAl2O4 催化剂上进行甘油水相转化

甘油是生物柴油生产过程中丰富的副产物，水相重整制氢已被证明是处理甘油的有效方法。本研究利用Pt/NiAl2O4催化剂研究了甘油的APR，旨在开发一种可持续的生物柴油副产品制氢方法。与传统支架相比，NiAl2O4具有更好的热稳定性和抗相变能力。表征技术表明，NiAl2O4载体增强了Pt颗粒的分散性和稳定性，有助于将甘油转化为99.9%的气态产物，寿命超过530小时（仅损失2%）。研究结果表明，Pt/NiAl2O4可有效促进脱氢和水煤气转换反应，从而突出了其在APR生物制氢中的应用潜力。
