| 摘 要： | 阿尔伯塔的油砂资源日益成为北美重要的战略性能源供给.本实验室通过采用碱性条件下在高岭土表面上组装菱沸石的方法,合成了新型的菱沸石-粘土复合材料,并证明此复合材料是比菱沸石更好的油砂沥青精制剂.XRD,SEM,TEM,N2物理吸附和XPS表面元素分析结果表明,菱沸石-粘土复合材料具有大体积烃类分子可及的独特的外表面,该复合材料不仅可降低油砂沥青的裂解反应温度,同时还可大幅度脱除沥青中的硫、氮、镍和钒等杂质.

| Abstract: | The Alberta oilsands resource is increasingly recognized as a strategic source for North American energy supply. We synthesized a novel chabazite-clay composite for improved oilsand bitumen upgrading by growing chabazite on kaolin under alkaline conditions. XRD,SEM,TEM,N2 physical adsorption,and XPS surface elemental analysis confirmed that the chabazite-clay composite has a unique exterior surface,accessible to large hydrocarbon molecules,that could moderate bitumen upgrading reaction with high performance contaminant (sulfur,nitrogen,nickel,and vanadium) removal. |
