2015 : Hydrocracking of Nyamplung Oil (Calophyllum inophyllum 0il) Using CoMo/γ-Al2O3 and CoMo/SiO2 Catalysts

Prof. Dr. Ir. Achmad Roesyadi M.Sc


The purpose of this research is to study hydrocracking process of nyamplung oil using 5% and 15% CoMo catalyst and supported on γ-Al 2 O 3 and SiO 2. Catalyst was prepared using wet impregnation method and calcined at 500 o C for 5 hours without sulfidation process. The X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were performed to analyze the crystalinity and surface morphology. Based on the XRD that MoO 2 was deposited on the surface of the catalysts. The hydrocracking of nyamplung (Calophyllum inophyllum) oil was conducted in Parr pressure reactor at 350 o C and 3 MP. Hydrocracking product was analyzed by using Gas Cromotography–Mass Spectrometry (GCMS). The highest catalytic activity was obtained by 15% loading CoMo over γ-Al 2 O 3 and the highest yields were 39.58% gasoil, 31.32% gasoline and 7.44% kerosene.
