模板剂去除方法对介孔分子筛材料的理化性质有重要影响。为了更好地了解模板剂去除方法与Ni/Al-SBA-15性能的关系，介绍了4种模板剂去除方法，分别用于去除Al-SBA-15中的有机模板剂。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、X射线荧光（XRF）、粉末X射线衍射（XRD）、N2吸附、傅里叶变换红外光谱（FT-IR）、吡啶吸附红外光谱（Py-FTIR）、魔角旋转核磁共振（MAS-NMR）、X射线光电子能谱（XPS）和气相色谱-质谱（GC-MS）。采用两步焙烧法去除有机模板剂后的Ni/Al-SBA-15具有最大的比表面积（619 m2/g）。相比之下，Ni/Al-SBA-15，其中的有机模板剂使用溶剂萃取方法去除具有最低的比表面积（555 m2/g）。采用电加热消解法去除模板剂后，Ni/Al-SBA-15的中孔孔径显著增大，孔壁厚度显著减小，为11.62 nm。研究了丁香酚加氢脱氧过程中产物的选择性。在Ni/Al-SBA-15催化剂上，采用溶剂萃取法脱除有机模板剂，加氢脱氧得到高烃类。与直接焙烧法相比，两步焙烧法能更有效地去除模板剂，所制备的催化剂更适合加氢脱氧反应。
Template removing approaches can significantly impact the physiochemical properties of mesoporous molecular sieve materials. In order to better understand the relationship between template removing approaches and the properties of Ni/Al-SBA-15, four kinds of template removing approaches were introduced to remove the organic template from Al-SBA-15, respectively. The structural characteristics of these materials were analyzed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray fluorescence (XRF), powder X-ray diffraction (XRD), N2-sorption, Fourier transform infrared spectra (FT-IR), infrared spectra of pyridine adsorption (Py-FTIR), magic angle spinning-nuclear magnetic resonance (MAS-NMR), X-ray photoelectron spectroscopy (XPS) and gas chromatography-mass spectrometry (GC-MS). Ni/Al-SBA-15 of which the organic template was removed by two-step calcination method had the maximum specific surface area (619 m2/g). In contrast, Ni/Al-SBA-15 of which the organic template was removed using solvent extraction approaches had the lowest specific surface area (555 m2/g). The mesopore diameter of Ni/Al-SBA-15, using electric heating digestion method to remove the template, was significantly increased and the wall thickness was significantly decreased to 11.62 nm in comparison with the other samples. The selectivity of products during the process of eugenol hydrodeoxygenation was investigated. High hydrocarbons were obtained during catalytic hydrodeoxygenation over Ni/Al-SBA-15 of which the organic template was removed by using solvent extraction approaches. Compared with direct calcination process, two-step calcination was more effective in removing template and the corresponding catalyst was much more suitable for the hydrodeoxygenation process.
