英文摘要: A series of NiZnAl catalysts have been developed for the hydrogen production by methanol steam reforming within microchannel reactor. These catalysts were characterized by N-2 adsorption-desorption, X-ray diffraction, H-2-TPR and pulse H-2-chemisorption. Our results show that the coexistence of Ni and Zn in bimetallic catalysts results in superior catalytic performance for hydrogen production compared with monometallic catalysts, despite the fact the former possesses the lower surface area. The difference between the catalytic performances could mainly be attributed to the Ni promotion effect associated with SMSI-like geometric effects and interpreted by a hypothesized encapsulation model corroborated by the characterizations.
