Current research focuses on hydrogen production from ethanol steam reforming (ESR) followed by water‐gas shift (WGS) reaction. Ce‐Ni/MCM‐41 and Fe/Ce/M (where M = K, La, Ti) catalysts were prepared by the wet‐impregnation technique and used for the ESR and WGS reactions, respectively. All experiments were carried out at 600 °C. The effects of the reduction time, the ratio of the two catalysts, and their arrangement were also investigated. The best results were obtained using Fe/Ce/Ti as WGS catalyst and with a separate array because the H₂ production and CO₂ level in the product gas were improved while that of CO was reduced. To generate high‐purity hydrogen, the CaO‐based adsorbent was used as a third layer to adsorb CO₂ from the gaseous products.

乙醇蒸汽重整，然后在Ce-Ni / MCM-41和铁基催化剂上进行水煤气变换反应

目前的研究集中在乙醇蒸汽重整（ESR）和随后的水煤气变换（WGS）反应制氢。Ce-Ni / MCM-41和Fe / Ce / M（其中M = K，La，Ti）催化剂是通过湿法浸渍技术制备的，分别用于ESR和WGS反应。所有实验均在600°C下进行。还研究了还原时间，两种催化剂的比例及其排列的影响。使用Fe / Ce / Ti作为WGS催化剂并使用单独的阵列可获得最佳结果，因为提高了产物气中的H ₂生成量和CO ₂含量，同时降低了CO含量。为了产生高纯度氢气，将基于CaO的吸附剂用作第三层，以吸附气态产物中的CO ₂。
