A process for the conversion of fused two-ring aromatic and fused two-ring hydroaromatic hydrocarbons into lower boiling aromatics, particularly alkylbenzenes of higher octane values. Such feeds are contacted in the presence of hydrogen over an iron catalyst at temperature sufficient to selectively hydrogenate and hydrocrack said fused two-ring aromatic hydrocarbon compound, or fused two-ring hydroaromatic hydrocarbon compounds, or both, to produce lower molecular weight, higher octane components suitable for direct blending with gasoline.

A process 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 an admixture of fused two-ring aromatic hydrocarbons and fused two-ring hydroaromatic hydrocarbons, having an initial boiling point of at least about 177°C. (350°F.), to lower boiling, higher octane hydrocarbons which comprises: contacting said 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°C. to about 430°C. and hydrogen partial pressure ranging from about 0 psig to about 1000 psig sufficient to selectively hydrogenate and hydrocrack said fused two-ring aromatic hydrocarbon compound, or fused two-ring hydroaromatic hydrocarbon compound, or both, to produce a lower molecular weight, higher octane product.
