Abstract
The impacts of climate change and the issue of greenhouse gas emissions have sparked research into renewable energy alternatives to fossil fuels. Hydrogen has gained attention as a clean, renewable and environmentally friendly energy source. Enhanced-ethanol steam reforming has been proposed as a promising method for blue hydrogen production, addressing greenhouse gas emission issues. The use of catalysts enhances the adsorption of ethanol and water molecules on the surface, promoting the reaction rate. This study systematically explored the effects of different Fe loading and CaO addition ratios on the ethanol steam reforming and CO2 conversion processes to optimize catalyst performance. The experimental results showed that Fe/SiC catalysts effectively promoted the conversion of ethanol and generated high-purity hydrogen, exhibiting excellent catalytic activity. Specifically, a catalyst with 10 % Fe loading and mixed with 0.3g CaO significantly increased the hydrogen yield to 64.4 mmol/g, which was 2.88 times higher than that without the catalyst.
气候变化的影响和温室气体排放问题引发了对化石燃料的可再生能源替代品的研究。氢气作为一种清洁、可再生和环保的能源受到了关注。有人提出，强化乙醇蒸汽转化是一种很有前途的蓝色制氢方法，可以解决温室气体排放问题。催化剂的使用可增强乙醇和水分子在催化剂表面的吸附，从而提高反应速率。本研究系统地探讨了不同 Fe 负载和 CaO 添加比对乙醇蒸汽转化和 CO2 转化过程的影响，以优化催化剂性能。实验结果表明，Fe/SiC 催化剂能有效促进乙醇转化并产生高纯度氢气，表现出优异的催化活性。具体而言，铁含量为 10% 并与 0.3g CaO 混合的催化剂可显著提高氢气产量，使其达到 64.4 mmol/g，是未添加催化剂时的 2.88 倍。
