Abstract

Hydrogen production via steam reforming (SR) is technically and economically feasible. To achieve higher feedstock conversion and H₂ yield, this study reviews the key parameters affecting SR, including feedstock type, temperature, steam-to-carbon molar ratio, pressure, space velocity, catalyst type, and reactor type. Accordingly, optimal parameter values must be selected considering thermodynamic, kinetic, and economic conditions. In addition, the challenges and prospects of the SR process are explored. Significant limitations of the SR process include overdependence on fossil fuels, CO₂ emissions, high energy requirements, catalyst deactivation, heat management, and infrastructure development. However, adopting renewable and sustainable feedstocks such as biogas, renewable energy sources like wind, solar, hydropower, tidal, and geothermal, smaller-scale SR, and carbon capture utilization, and storage technology can ensure that SR remains a viable H₂ production method alongside the increasing adoption of greener alternatives.

影响制氢蒸汽重整性能的关键参数

蒸汽重整制氢在技术上和经济上都是可行的。为了实现更高的原料转化率和H2产率，本研究回顾了影响SR的关键参数，包括原料类型、温度、汽碳摩尔比、压力、空速、催化剂类型和反应器类型。因此，必须考虑热力学、动力学和经济条件来选择最优参数值。此外，还探讨了SR工艺面临的挑战和前景。SR工艺的重大局限性包括过度依赖化石燃料、二氧化碳排放、高能耗、催化剂失活、热管理和基础设施建设。然而，采用可再生和可持续的原料，如沼气，风能、太阳能、水电、潮汐能和地热等可再生能源，小规模的SR，以及碳捕获利用和储存技术，可以确保SR仍然是一种可行的制氢方法，同时越来越多地采用更环保的替代品。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
