Hydrogen production from steam reforming of bioethanol using Cu/Ni/K/γ-Al_2O_3 catalysts. Effect of Ni

摘要

Hydrogen to be used as a raw material in fuel cells or even as a direct fuel can be obtained from steam reforming of bioethanol. The key aim of this process is to maximize hydrogen production, discouraging at the same time those reactions leading to undesirable products, such as methane, acetaldehyde, diethyl ether or acetic acid, the compete with H_2 for the hydrogen atoms. Cu-Ni-K/γ-Sl_2O_3 catalysts are suitable for this reaction since they are able to produce acceptable amounts of hydrogen working at atmospheric pressure and a temperature of 300 deg. C.
