Hydrocracking process of Butonian asphalt derived asphaltene using Mo-Ni/γ-alumina catalyst has been investigated. The processes were carried out in 1L stainless steel autoclave reactor. The reaction temperatures were 250, 300, 350 and 400C, initial pressure was 10 atm and catalyst/feed ratio was 1/2. The asphaltene was a pentane insoluble-benzene soluble (PI-BS) fraction of Butonian asphalt.The results of hydrocracking processes showed the conversion by means of 100% - coke (wt %) was followed equation konversi % (w/w) = 0,306 t (C) - 41,29Key words: hydrocracking, asphaltene, Mo-Ni/γ-alumina catalyst
