    • Processes and apparatuses for preparing aromatic compounds are provided. In an embodiment, a process of preparing aromatic compounds includes providing a heavy reformate stream including C7 hydrocarbons, xylenes, styrene, and compounds having more than 8 carbon atoms. The xylenes and styrene are separated from the compounds that have more than 8 carbon atoms in the heavy reformate stream to form a mixed xylene stream including the xylenes and styrene and a C9+ stream including compounds with less volatility than C8 aromatics. The styrene within the mixed xylene stream is selectively hydrogenated to form a hydrogenated xylene stream including xylenes and ethylbenzene. At least some of the xylenes are separated from the ethylbenzene in the hydrogenated xylene stream to form a C8 raffinate stream including the ethylbenzene and a xylene product stream including one or more xylene species.
