Many catalysts will work, including; nickel, palladium, platinum, cobalt, and iron in hydrotreating which involves temperatures of about 325°C and pressures of about 50 atm. Hydrocracking that breaks longer molecules into smaller ones, involves temperatures over 350°C and pressures up to 200 atm. In both cases, very long residence times (about an hour) are required because of the slow nature of the reactions. In this study, feasibility of catalytic thermal cracking was investigated and compared through thermal decomposition behavior of vacuum residual oils over iron and nickel oxide catalysts which prepared on silicate as a support using glycine-nitrate combustion method and wet impregnation method.
