Abstract

Impregnation of nickel cloride onto the Y-zeolite and their ulitilization for hydrocracking catalyst have be done. The synthetic Y-zeolite was modificated by added of ammonium nitrat 2 M, then these were calcinated for 5 hours at 450oC. Furhter, the product was impregnated with nickel cloride in ethanol. The concentration of nickel cloride solution were 0,4 %, 0,6%, 0,8%, 1,0%, 1,2% and 1,6%, respectively. The character of Ni/Y-zeolite and H/Y-zeolite were conducted by measuring nickel content and crystallinity. Activity test of catalyst was carried out in hydrocracking procees at 350oC and 150-230oC fraction of Minas Crude Oil was used as feed. Finally, the liquid product was analyzed by gas chromatograph-mass spectroscopy. The result of this experiment showed that nickel content onto H/Y zeolite after impregnation process increase. From the measuring of crystallinity, it has been known that relative crystallinity of H/Y-zeolite after impregnation was decrease about 26 – 28%. The test of activity showed that the highest of CHP was 55% (loaded Ni 2,51%). In addition, we got information that Ni/Y were able to convert the C13-C23 coumpound of the feed, to produce the C7-C10 as new coumpound.
