ABSTRACT:
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.
