The presented article shows the studies of hydrocracking process of fuel oil with the purpose of obtaining light oil products (benzene and diesel fractions) from heavy oil residues (fuel oil), thus, deepening the refining of oil. The hydrocracking of fuel oil was conducted in the presence of halloysite modified with transition metals (Mo, Ni). Toward this end, halloysite was modified by two different methods—absorption and ion-exchange methods. It was shown that, at optimal conditions (430 °C, 4 MPa), 46.6% (wt.), 53.0% (wt.), 63.0% (wt.) and 83.0% (wt.) light oil products are obtained by the hydrocracking process of fuel oil carried out without catalyst, in the presence of unmodified halloysite, halloysite modified by absorption method and halloysite modified by ion-exchange method, respectively. The obtained benzene and diesel fractions after hydrorefining process can be added to fuels as components.
