Abstract

THE EFFECTIVTY OF Co/Mo CATALYSTS IN HYDROCRACKING OF NYAMPLUNG OIL. Hydrocracking process of Nyamplung Oil was presented using Co and Mo as metal catalysts. Ratio of CoMo metals in catalysts, can give better catalytic activity for Nyamplung Oil conversion. In this process, we used Co/Mo ratio (0.264/0.64), (0.62/1.61), and (1.23/3.22) towards SiO₂ dan γ-Al₂O₃. This catalyst has made by wet impregnation method with drying temperature at 383 K during 8 hours and was calcined at 773 K for 5 hours. This catalyst was characterized by X-Ray Diffraction (XRD) and showed Co₃O₄, MoO₃ and CoMoO₄substances that was deposited at CoMo/SiO₂ catalyst surface. Then, Co₃O₄, MoO₃, MoO₂ and CoMoO₄substances was also appeared at CoMo/γ-Al₂O₃ catalyst surface. That all phases which is deposited at both of this catalyst surface, is appropriate with International Centre for Diffraction Data (ICDD standards). Then, this catalyst was used for hydrocracking process of Nyamplung Oil that takes place at batch reactor. That process was carried out at 3 MPa and 623 K over 2 hours. C₅-C₁₁ dan C₁₂-C₁₈products was produced from Nyamplung Oil conversion using this process. Both of this products is increased correspond to the addition of Co and Mo metals ratio. The highest yield that was achieved is C₅-C₁₁ (24.30%) and C₁₂-C₁₈ (61.28%) when using Co/Mo (1.23/3.22)/γ-Al₂O₃ catalyst. Meanwhile, Co/Mo (1.23/3.22)/ SiO₂ catalyst can produce C₅-C₁₁ (19.52%) and C₁₂-C₁₈ (53.55%).
