| 摘 要： | 采用晶化培育法制备了L沸石纳米晶簇,以其作为前驱体,并以3-三甲基甲硅烷基丙基十六烷基二甲基氯化铵(TPHAC)为模板剂,合成了微孔-介孔多级孔道L沸石(MeLTL沸石).通过X射线衍射(XRD)、氮气吸附-脱附、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、27Al固体魔角核磁(27AlMASNMR)和吡啶傅立叶变换红外(Py-FTIR)等方法对MeLTL沸石进行了表征.研究结果表明,MeLTL沸石是由L沸石纳米晶簇自组装形成的,并具有介孔孔道和L沸石的微孔结构以及适宜的酸量与酸强度,其比表面积和孔体积分别高达611m2.g-1和0.696cm.3g-1.将MeLTL沸石作为添加剂引入柴油加氢脱硫催化剂载体中,并与添加L沸石、Al-MCM-41和仅以γ-Al2O3为载体的催化剂进行比较,其脱硫性能为最佳,经加氢后的柴油硫含量仅为9.3μg.g-1,脱硫率达99.3%.

| Abstract: | Zeolite MeLTL with a micro-mesoporous composite pore structure was synthesized by using nanocrystal clusters of zeolite L prepared by the crystallization nurturing method as a precursor and [3-(trimethoxysilyl)propyl] hexadecyldimethylammonium chloride (TPHAC) as the organic mesopore directing surfactant. Several techniques including X-ray diffraction (XRD),nitrogen adsorption-desorption,scanning electron microscopy (SEM),transmission electron microscopy (TEM),27Al magic angle spinning nuclear magnetic reso... |
