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.
