A process is described for the conversion of a feed comprised of hydrocarbon compounds selected from the group consisting of a fused two-ring aromatic hydrocarbon compound, a fused two-ring hydroaromatic hydrocarbon compound, and a admixture of fused two-ring aromatic hydrocarbons and fused two-ring hydroaromatic hydrocarbons, having an initial boiling point of at least about 177/sup 0/C (350/sup 0/F) to lower boiling, higher octane hydrocarbons which comprises: contacting the feed, in the presence of hydrogen,over a catalyst comprised of elemental iron and one or more alkali or alkaline-earth metals components at a temperature ranging from about 225/sup 0/C to about 430/sup 0/C and hydrogen partial pressure ranging from about 0 psig to about 1000 psig sufficient to selectively hydrogenate and hydrocrack the fused two-ring aromatic hydrocarbon compound.
