The increase in biodiesel production is leading to a scenario in which more glycerol, which is a by-product of this biofuel production, is generated each day. Among the many potential applications for this substance, steam reforming is emerging as an alternative for solving the glycerol utilization problem, while also providing a new and potentially green source of fuel. In this study, an exergoenvironmental analysis of this process for high-purity hydrogen production was carried out based on data obtained from an Aspen HYSYS® V11 process simulation. Three different scenarios regarding reform gas processing were evaluated from both technical and environmental points of view. Despite the high concentration of water and CO₂ in the residual gas obtained after H₂ purification, recycling this flow was found to maximize glycerol reforming capacity, while also increasing the system's overall exergy efficiency. For all of the scenarios evaluated through exergy analysis, the environmental impact associated to hydrogen production through glycerol steam reforming was found to be lower than the values reported for methane, indicating that this by-product may be a suitable feedstock for decreasing the environmental impact caused by the use of fossil fuels for hydrogen production.

生物柴油产量的增加导致每天产生更多甘油的情况，甘油是这种生物燃料生产的副产品。在该物质的许多潜在应用中，蒸汽重整正在成为解决甘油利用问题的替代方法，同时也提供了一种新的，潜在的绿色燃料来源。在这项研究中，基于从AspenHYSYS®V11过程仿真获得的数据，对该过程进行了高纯度制氢的环境分析。从技术和环境角度评估了关于重整气处理的三种不同方案。尽管在H ₂之后获得的残留气体中水和CO _2的浓度很高纯化，循环利用该物流可最大程度地提高甘油的重整能力，同时还可以提高系统的整体火用效率。对于所有通过火用分析评估的方案，发现与甘油蒸汽重整制氢相关的环境影响低于所报道的甲烷值，这表明该副产物可能是降低环境影响的合适原料。通过使用化石燃料生产氢气。
