The catalyst carriers, SBA-15, the layer compounds such as the silica-pillared H+-kenyaite(SPK) and H+-magadite(SPM) were prepared for partial oxidation of methane(POM) to hydrogen. The adsorption isothern of SBA-15 was the type IV that the mesopores were well developed with hysteresis. The BET surface area and BJH adsorption average pore diameter were 931 m2/g and 30Å, respectively. The BET surface area and the Horvath-Kawazoe pore distributions of SPM and SPK were 810 m2/g and 2.6 nm for SPM and 760 m2/g and 3.0 nm for SPK. The adsorption isothern of SPM and SPK also were the type IV well defined. The TEMs of SPM and SPK showed the layer compounds of narrow well formed. It proposed that the the carriers made by our method could be used for partial oxidation of methane(POM) to hydrogen. |
