Abstract

Graphical abstract: Different fuel range alkanes can be synthesized from hydroprocessing castor oil by Ni supported on different acidic zeolites, and bio-aviation fuel can be obtained by Ni supported on moderate acidic strength zeolites. Highlights: Bio-aviation fuel was firstly synthesized by hydroprocessing castor oil. Castor oil was converted into aviation fuel by the two-step process and a one-pot process respectively. The degree of hydrodeoxygenation and hydrocracking could be adjusted by Ni supported on moderate acidic zeolites. Abstract: Bio-aviation fuel was firstly synthesized by hydroprocessing castor oil in a continuous-flow fixed-bed microreactor with the main objective to obtain the high yield of aviation fuel and determine the elemental compositions of the product phases as well as the reaction mechanism. Highest aviation range alkane yields (91.6 wt%) were achieved with high isomer / n-alkane ratio ( i / n ) 4.4–7.2 over Ni supported on acidic zeolites. In addition, different fuel range alkanes can be obtained by adjusting the degree of hydrodeoxygenation (HDO) and hydrocracking. And the observations are rationalized by a set of reaction pathways for the various product phases.
