Webhydrogen has been produced from catalytic steam reforming of fossil fuels, for example, methane [1]. To reduce greenhouse gas emissions, hydrogen should be derived from renewable energy sources such as bio-ethanol [2–4]. As a consequence, ethanol steam reforming has been studied, as it provides an alternative fuel source for hydrogen ... WebSteam Methane Reforming, or SMR, processes feedstocks, ranging from natural gas to light naphtha, mixed with steam to produce a hydrogen-rich syngas effluent, with a typical H2/CO ratio of 3:1 to 5:1. SMR based plants are most commonly used to produce a hydrogen product or a combination of a hydrogen stream and another syngas product.
