A process for treating a hydrocarbon-containing feedstock is provided in which a hydrocarbon-containing feedstock comprising at least 20 wt. % of heavy hydrocarbons is mixed with hydrogen and a non-acidic metal-containing catalyst at a temperature of 375&#xb0; C. to 500&#xb0; C. to produce a vapor comprising a first hydrocarbon-containing product. The vapor comprising the first hydrocarbon-containing product is separated from the mixture, and, apart from the mixture, the first hydrocarbon-containing product is contacted with hydrogen and a catalyst containing a Column 6 metal at a temperature of 260&#xb0; C.-425&#xb0; C. to produce a second hydrocarbon-containing product. The second hydrocarbon-containing product is separated into fractions, one of the fractions being a heavy hydrocarbon fraction comprised of hydrocarbons having a boiling point of at least 343&#xb0; C. The heavy hydrocarbon fraction is then contacted with a fluidizable cracking catalyst at a temperature of at least 500&#xb0; C.
