Innovative pressurized diesel reforming for sustainable hydrogen production using advanced PtRu-CGO catalyst

Abstract

This study suggests a novel approach for producing hydrogen through the pressurized reforming of commercial diesel, leveraging the PtRu-CGO catalyst. Foundational experiments were performed with PtRu-CGO powder catalysts at conditions up to 9 bar and 800 °C, achieving complete fuel conversion and stable performance with an average hydrogen concentration of approximately 58.7 mol%. Additionally, the structured catalysts developed herein also could maintain high efficiency and durability under a gas hourly space velocity (GHSV) of 10,000 h⁻¹. Notably, at 6 bar, the system exhibited an extraordinary efficiency of around 75 % over 300 h of continuous operation. These results underscore the practicality of pressurized diesel reforming for hydrogen production with the PtRu-CGO catalyst, highlighting its potential in the development and optimization of hydrogen energy systems and aiding the shift towards a hydrogen-based economy.
