The catalytic steam reforming of oxygenated hydrocarbons has been holding an interest in scientific societies for the past two decades. The hydrogen production from steam reforming of glycerol, ethanol and other oxygenates such as ethylene glycol and propylene glycol are more suitable choice not just because it can be produced from renewable sources, but it also helps to decrease the transportation fuel price and making it more competitive. In addition, hydrogen itself is a green fuel for the transportation sector. The studies on the production of hydrogen from various reforming technologies revealed a remarkable impact on the environmental and socio-economic issues. Researchers became more focused on glycerol steam reforming (GSR), ethanol steam reforming (ESR) and other oxygenates to investigate the catalyst suitability, their kinetics and challenges for the sustainability of the oil and gas production. In the present work, the authors critically addressed the challenges and strategies for hydrogen production via GSR, ESR and other oxygenates reforming process. This review covers extensively thermodynamic parametric analysis, catalysts developments, kinetics and advancement in the operational process for glycerol, ethanol and few other oxygenates. This detailed investigation only highlights the steam reforming process (SRP) of these oxygenates at the laboratory experimental stage. It was found that from this review, there are many technical issues, which lead to economic challenges. The issues are yet to be addressed and thus, these particular applications require faster accelerations at the pilot scale, taking into the consideration of the current pandemic and economic issues, for a safer and greener environment.

在过去二十年中，含氧烃的催化蒸汽重整一直受到科学界的关注。通过甘油、乙醇以及其他含氧化合物（如乙二醇和丙二醇）的蒸汽重整来制氢是更合适的选择，这不仅是因为这些含氧化合物可由可再生资源制得，还因为它有助于降低运输燃料价格，使其更具竞争力。此外，氢气本身就是运输领域的绿色燃料。对各种重整技术制氢的研究表明，这对环境和社会经济问题有着显著影响。研究人员更加关注甘油蒸汽重整（GSR）、乙醇蒸汽重整（ESR）以及其他含氧化合物，以研究催化剂的适用性、反应动力学以及油气生产可持续性面临的挑战。在本研究中，作者批判性地探讨了通过GSR、ESR以及其他含氧化合物重整过程制氢所面临的挑战和策略。本综述广泛涵盖了甘油、乙醇和其他几种含氧化合物的热力学参数分析、催化剂开发、反应动力学以及操作过程的进展。这项详细的研究仅突出了这些含氧化合物在实验室实验阶段的蒸汽重整过程（SRP）。从本次综述中发现，存在许多导致经济挑战的技术问题。这些问题尚待解决，因此，考虑到当前的疫情和经济问题，为了营造一个更安全、更绿色的环境，这些特定应用需要在中试规模上更快地加速推进。图形摘要。
