| Summary: | ABSTRACT
Preparation, characterization, and catalytic activity test of Ni-Moinatural zeolite on pyridine hydrodenitrogenation were carried out. Preparation of catalyst was conducted by impregnation method using nickel nitrate hexahydrate and ammoniumheptamolibdateprecursor as Ni and Mo source respectively. Characterizationof
catalyst was conducted by using gravimetry, atomic absorption spectrophotometry, and X-ray diffraction method.Catalytic activity test on pyridine hydrodenitrogenationwas carried out by using flow system reactor with hydrogen flow rate variable. The research results showed that the catalyst's total acidity and crystallinity are increased with level of impregnation success of 96.71% and 90.08% respectively. Ni-Mo/natural zeolites able to increase the
catalytic conversion up to 71.78% at 350°C and hydrogen flow rate of 10 mUmin with more highly varied product distribution.Assuming that the pyridine hydrodenitrogenationfollows the pseudo first order kinetics
