| 摘 要： | 分别以正硅酸乙酯(TEOS)和Na2SiO3为硅源,室温合成了Cu∶Zn∶Al∶Si摩尔比为6∶3∶5∶100的类MCM-41催化剂,以XRD、N2吸附、氨吸附量热及异丙醇脱水/脱氢反应等表征了催化剂的性质.结果表明,两种催化剂均具有较好的介孔结构,以Na2SiO3为硅源的催化剂具有较强的酸性.甲醇水蒸气重整反应表明,以TEOS为硅源的催化剂对甲醇转化率和H2选择性均高于以Na2SiO3为硅源的催化剂. |

| Abstract: | The MCM-41-like catalysts of 6Cu/3Zn/5Al/100Si(mol ratio) were synthesized at room temperature(RT) with TEOS and Na_2SiO_3 as Si sources.XRD and N_2 adsorption results suggested that both catalysts had the ordered mesoporous structures.Microcalorimetric adsorption of NH_3 and isopropanol probe reaction indicated that the catalyst synthesized with Na_2SiO_3 showed higher acidity.The catalyst synthesized with TEOS exhibited higher activity for methanol conversion and selectivity to H_2 in reforming of methanol for H_2 production. |
| Keywords: | 6Cu3Zn5Al-MCM-41 XRD microcalorimetric adsorption isopropanol reaction methanol steam reforming H_2 production |
