“…Pigos et al [8] reported that the addition of Na and K significantly improved the formate decomposi-tion rate on a WGS reaction over Pt/ZrO 2 catalysts. Wang et al [9] reported that the addition of Na improved the catalytic performance of a PtRu/ZrO 2 catalyst on the oxidative steam reforming of ethanol, where the Na not only enhanced the WGS reaction at a low temperature, but also reduced coke deposition. Cheng et al [10] also reported the promotional effect of doping alkaline earth oxides or lanthanide oxides on a Ni/Al 2 O 3 catalyst for CO 2 reforming of CH 4 .…”

Hydrogen production through steam reforming of ethanol (SRE) over Mg modified Co-based catalysts supported on mesoporous SBA-15 was studied herein to evaluate the catalytic activity and the behavior of coke deposition. The Co y Mg x /SBA-15 catalysts are obtained according to the steps of consecutive impregnation of Mg (x = 5 and 10 wt%) to be incorporated on SBA-15 and then follow the loading of Co (y = 10 and 20 wt%) using the incipient wetness impregnation method. The catalysts are characterized by using X-ray diffraction (XRD), temperature programmed reduction (TPR), transmission electron microscopy (TEM) and BET techniques. Also, the spent catalysts are further characterized by using XRD and TEM. The catalytic activity of the SRE is evaluated in a fixed-bed reactor under 22,000 h −1 GHSV and with an H 2 O/EtOH molar ratio of 13. All the Co y Mg x /SBA-15 catalysts present a mesoporous structure, even after the SRE reaction. The optimum catalyst of Co 20 Mg 5 /SBA-15-H650 comes from the high loading of Co and high reduction temperature pretreatment, which show a high catalytic activity and stability at 550˚C with a hydrogen yield (Y H2 ) up to 5.78 and CO selectivity around 3.10%.

Hydrogen production through steam reforming of ethanol (SRE) over the Ca-modified Co/SBA-15 catalysts was studied herein to evaluate the catalytic activity, stability and the behavior of coke deposition. The Ca-modified SBA-15 supports were prepared from the Ca(NO 3 ) 2 ·4H 2 O (10 wt %) which was incorporated to SBA-15 by incipient wetness impregnation (assigned as Ca/SBA-15) and direct hydrothermal (assigned as Ca-SBA-15) method. The active cobalt species from the Co(NO 3 ) 2 ·6H 2 O (10 wt %) was loaded to SiO 2 , SBA-15 and modified-SBA-15 supports with incipient wetness impregnation method to obtain the cobalt catalysts (named as Co/SiO 2 , Co/SBA-15, CoCa/SBA-15 and Co/Ca-SBA-15, respectively). The prepared catalysts were characterized by using Xray diffraction (XRD), temperature programmed reduction (TPR), transmission electron microscopy (TEM) and BET. The catalytic performance of the SRE reaction was evaluated in a fixed-bed reactor. The results indicated that the Co/Ca-SBA-15 catalyst was preferential among these catalysts and the ethanol can be converted completely at 375 °C. The hydrogen yield (Y H2 ) approached 4.76 at 500 °C and less coke deposited. Further, the long-term stability test of this catalyst approached 100 h at 500 °C and did not deactivate.
