Catalytic pyrolysis of Undaria Pinnatifida was carried out over a nanoporous Al-SBA-15 catalyst for the first time. Pt nanoparticles were added to Al-SBA-15 to generate a Pt/Al-SBA-15 catalyst. The effect of the addition of the Pt nanoparticles on the catalytic pyrolysis was investigated. For rapid product analysis and catalyst evaluation, a pyrolysis-gas chromatography/mass spectrometry was used. The characteristics of the catalysts were analyzed using X-ray diffraction, nitrogen adsorption-desorption, transmission electron microscope, NH3 temperature programmed desorption, and inductively coupled plasma optical emission spectrometer. Compared to the non-catalytic pyrolysis, catalytic pyrolysis over Al-SBA-15 produced a higher-quality bio-oil with a high stability and a low oxygen content. When Pt/Al-SBA-15 was used, compared to Al-SBA-15, the improvement of bio-oil quality was more profound; the yield of high-value-added aromatics increased, while the yields of acids and oxygenates decreased.
首次在纳米多孔Al-SBA-15催化剂上对海带进行催化热解。将铂纳米颗粒添加到Al-SBA-15中以制备Pt/Al-SBA-15催化剂。研究了添加铂纳米颗粒对催化热解的影响。为了快速进行产物分析和催化剂评价，采用了热解-气相色谱/质谱联用技术。使用X射线衍射、氮气吸附-脱附、透射电子显微镜、氨程序升温脱附以及电感耦合等离子体发射光谱仪对催化剂的特性进行了分析。与非催化热解相比，在Al-SBA-15上进行的催化热解产生了质量更高、稳定性高且氧含量低的生物油。当使用Pt/Al-SBA-15时，与Al-SBA-15相比，生物油质量的改善更为显著；高附加值芳烃的产率增加，而酸和含氧化合物的产率降低。
