A process for aromatizing hydrocarbons comprises: converting at least a portion of highly branched hydrocarbons in a feed stream into selectively convertible components, and aromatizing the selectively convertible components to produce an aromatization reactor effluent. The aromatization reactor effluent comprises an aromatic product. Converting at least the portion of the highly branched hydrocarbons into the selectively convertible components may include contacting the feed stream with an isomerization catalyst in an isomerization reaction system under isomerization reaction conditions; and isomerizing the portion of the highly branched hydrocarbons in the feed stream into the selectively convertible components.

The energy is minimized that is required to lower the concentration of the high boiling point components (containing the poisoning substance for the dehydrogenation catalyst) contained in the hydrogenated aromatic compound produced by the hydrogenation of an aromatic compound. The hydrogenation system (2) for an aromatic compound comprises a hydrogenation reaction unit (11) for adding hydrogen to an aromatic compound by a hydrogenation reaction to produce a hydrogenated aromatic compound, a first separation unit (12) for separating a gas and a liquid component from a product of the hydrogenation reaction unit while maintaining a temperature of the product generally higher than a boiling point of the hydrogenated aromatic compound, and a second separation unit (13) for separating the hydrogenated aromatic compound from the gas component separated by the first separation unit.

Methods and systems for selectively hydrogenating benzene with a supported organometallic hydrogenating catalyst are provided. An exemplary method includes contacting an arene-containing reaction stream comprising benzene and one or more additional arenes with hydrogen in the presence of a supported organometallic hydrogenating catalyst under reaction conditions effective to hydrogenate at least benzene in the arene-containing reaction stream to produce a reaction effluent having a ratio of benzene to additional arenes that is lower than a ratio of benzene to additional arenes in the reaction stream. In this method, the supported organometallic hydrogenating catalyst includes a catalytically active organometallic species and a Brnsted acidic sulfated metal oxide support.
