摘要：
Mo-promoted Ni/Al2O3 catalysts for the methane steam reforming reaction were studied in this work. The Ni/Al2O3 catalysts were prepared by precipitation and molibdenum was added by impregnation up to 2%wt. The solids were tested using a micro-reactor under two H(2)Ov/C conditions and were characterized by ICP-OES, XRD, N-2 adsoption, H-2 chemisorption and TPR. NiO and NiAl2O3 phases were observed and the metallic area decreased with the increase of the Mo content. From the catalytic tests high stability was verified for H(2)Ov/C=4.0. On the other hand, only the catalyst containing 0,05% Mo stayed stable during 30 hours of the test at H(2)Ov/C=2.0.
