Hydrocracking Reaction of n-Hexadekane Using Nickel-Natural Zeolite Catalyst and Determination of Activation Energy (Ea) and Reaction Order

Research has been carried out on the preparation of active natural zeolite impregnated with nickel followed by activity testing through hydrocracking catalytic reaction n-Hexadecane. Active was obtained from PT Prima Zeolita Yogyakarta. The concentration in sample ion exchange method [Ni(NH3)6]2+ precursor solution a 0.06M. content catalyst determined Atomic Absorption Spectrophotometer (AAS). used fixed bed reactor system. Ratio feed (n-Hexadecane) : = 3 1 (in gram). Catalysis study also at various temperatures, 315oC - 450oC certain content. results each temperature after passing cooling system there liquid fraction that had successfully accommodated then weighed and percent conversion. Furthermore, for determination Ea order using linear regression calculations. showed an Ni-Zeolite n-Hexadecane process resulted different conversion depending reaction. largest 450oC, which 35.18%. first-order (n=1). Meanwhile, activation energy or (Ea) Ni-Natural 2.0% (w/w) 127.071 kJmol-1.
