| 摘 要： | 以二乙胺为结构导向剂, 在微波条件下合成了SAPO-34分子筛材料, 并分别在空气和氮气氛下1073 K焙烧. 考察了氮气氛下分子筛表面碳改性后对材料表面及水、甲醇和乙醇吸附性能的影响. 结果表明: 碳改性后SAPO-34比表面、孔容下降, 但孔径趋于均一. 与SAPO-34样品相比, 碳改性后SAPO-34吸水量从0.295 g/g降低到0.180 g/g, 甲醇/乙醇的吸附比从1.42提高到2.81.

| Abstract: | In this paper, SAPO-34 was microwave-assisted synthesized with diethylamine as the struc- ture-director, and the synthesized samples were calcined under air and nitrogen at 1073 K respectively. The surface effect of carbon modified SAPO-34 under a nitrogen atmosphere and its adsorption ability to wa- ter/methanol/ethanol were studied. The results showed that the BET surface area and pore volume decrease, while pore diameter tends to be uniform on carbon-modified SAPO-34. Water-adsorption weight decreased from 0.295 g/g to 0.180 g/g, and the adsorption ratio of methanol/ethanol increased from 1.42 to 2.81 on the samples of carbon-modified SAPO-34 comparing with SAPO-34. |
