Abstract
Processes and apparatuses for preparing aromatic compounds are provided herein. In an embodiment, a process for preparing aromatic compounds includes providing a first stream that includes an aromatic component, a non-aromatic component, and a sulfur-containing component. The aromatic component and the sulfur-containing component are separated from the non-aromatic component of the first stream to form a separated aromatic stream and a raffinate stream. The separated aromatic stream includes the aromatic component and the sulfur-containing component. The raffinate stream includes the non-aromatic component. The separated aromatic stream is concurrently transalkylated and desulfurized in the presence of a catalyst that includes acid function and metal function to produce a transalkylated aromatic stream and a sulfur-containing gas stream that is separate from the transalkylated aromatic stream.
