以MOF材料为前驱体合成三维形貌的氧化铝(3DAO),采用低温水热法合成了具有分层纳米结构的勃姆石(HNγ-AlOOH),最后经煅烧形成相同纳米结构的活性氧化铝(HNγ-Al₂O₃)。以HNγ-Al₂O₃为载体制备了一系列负载量(0.5 %、1 %和1.5 %)的Pt/HNγ-Al₂O₃双功能催化剂,并将其用于油酸脱羧制备航空煤油。利用XRD、SEM、TEM、BET等对催化剂进行表征。结果表明,HNγ-Al₂O₃具有丰富的孔结构、较高的比表面积(266.8 m²/g)和适宜的酸性。1 % Pt/HNγ-Al₂O₃具有最优的催化性能,在反应温度为340 ℃、反应时间为5 h时,C₈~C₁₇的收率可达84.8 %。

Three-dimensional alumina (3DAO) is synthesized with MOF material as a precursor.Boehmite (HNγ-AlOOH) with a hierarchical nanostructure is synthesized through using a low-temperature hydrothermal method,and then calcined to form activated alumina (HNγ-Al₂O₃) with the same nanostructure.A series of Pt/HNγ-Al₂O₃ bifunctional catalysts with loading amounts of 0.5 %,1 % and 1.5 % respectively are prepared by using the as-prepared HNγ-Al₂O₃ as a carrier,and served for the decarboxylation of oleic acid to produce aviation kerosene.The catalysts prepared are characterized by means of XRD,SEM,TEM,BET,etc.It is found that HNγ-Al₂O₃ has rich pore structure,high specific surface area (266.8 m²·g^-1) and suitable acidity.The 1 % Pt/HNγ-Al₂O₃ has the best catalytic performance,over which the yield of C₈-C₁₇ alkanes can reach 84.8 % when the reaction temperature is 340℃and the reaction time is 5 h.
