中文摘要：

采用碘化N,N,N-三甲基-8-氨基-三环[5.2.1.02.6]癸烷为结构导向剂,通过过程控制方法,经3-4 d 成功合成了高性价比的B-SSZ-33 分子筛.以B-SSZ-33 为母体,经过Al（NO3）3溶液后处理制得了Al-SSZ-33 分子筛.采用X射线衍射（XRD）,傅里叶变换红外（FT-IR）光谱,扫描电子显微镜（SEM）,热重（TG）分析,电感耦合等离子体原子发射光谱（ICP-AES）,N2吸附/脱附,27Al 核磁共振（27Al NMR）和NH3程序升温脱附（NH3-TPD）等手段对合成的B-SSZ-33、Al-SSZ-33 样品进行了物理化学性能表征.并以甲苯作为汽车尾气中碳氢化合物的探针分子,通过甲苯程序升温脱附测试来考察样品的碳氢捕集性能.结果表明：后处理过程中Al 同晶取代B,从而制得了含骨架Al 的Al-SSZ-33; 在甲苯的程序升温脱附测试中,由于Al-SSZ-33 相对于B-SSZ-33 具有较强的酸性位,且表面孔口由于骨架外硅铝物种的修饰,限制了甲苯的扩散,致使脱附速率最大时的温度（Tmax）和脱附最终的温度（Tend）均升高,从而形成了新型汽车尾气捕集催化剂的雏形.

英文摘要：

Using N,N,N-trimethyl-8-ammonium tricyclo [5.2.1.0^2.6] decane iodide as a structure directing agent, B-SSZ-33 molecular sieves with an excellent price-performance ratio was successfully synthesized by process control over 3-4 days. The synthesis of AI-SSZ-33 was achieved by a post-modification procedure of B-SSZ-33 molecular sieves in an AI（NO3）3 solution. These materials were characterized in detail by various techniques such as X-ray diffraction （XRD）, Fourier transform infrared （FT-IR） spectroscopy, scanning electron microscopy （SEM）, thermogravimetric （TG） analysis, inductively coupled plasma-atomic emission spectroscopy （ICP-AES）, N2 adsorption/desorption, temperature programmed desorption of NH3 （NH3-TPD）, and solid state 27AI nuclear magnetic resonance （27AI NMR）. The temperature programmed desorption characteristics of toluene for the B-SSZ-33 and AI-SSZ-33 samples were obtained to understand the efficacy of these materials as hydrocarbon traps. The results show that Al-SSZ-33 with framework AI was obtained after the post-modification procedures. Compared with B-SSZ-33, Al-SSZ-33 has a higher acid strength and shows a comparatively higher toluene desorption temperature （Tmax）. The presence of extra framework AI and Si species in Al-SSZ-33 modifies its pores and results in a higher desorption end temperature （Tend）. Therefore, the synthesized AI-SSZ-33 is a novel catalyst for use as a hydrocarbon trap in automobile tailpipes.
