One of the methods to crack heavy oils into fuels with low molecular weight is hydrocracking. Hydrocracking catalysts which have three functions- hydrogenation by metals such as nickel and molybdenum, cracking by zeolite and diffusion by mesoporous materials such as silica, alumina, and silica-alumina. In this study, hydrocracking of atmospheric residue was investigated by zeolite-alumina composite supported NiMo catalysts. Curie point pyrolyzer was used to estimate the catalysts in the presence of hydrogen gas.
