Abstract:
1. A process for preparing aromatic compounds, the process comprising the steps of: providing a first stream comprising an aromatic component, a non-aromatic component, and a sulfur-containing component; separating the aromatic component and the sulfur-containing component from the non-aromatic component of the first stream to form a separated aromatic stream comprising the aromatic component and the sulfur-containing component and a raffinate stream comprising the non-aromatic component; feeding the separated aromatic stream comprising the aromatic component and the sulfur-containing component to a reactor containing a catalyst containing an acid function selected from the group consisting of MFI, MEL, MTW, FER, beta zeolite, mordenite, and acid promoted alumina, and a metal function selected from the group consisting of platinum, palladium, rhodium, ruthenium, osmium, iridium, rhenium, tin, germanium, lead, cobalt, nickel, molybdenum, indium, gallium, zinc, uranium, dysprosium, thallium, and mixtures thereof to transalkylate the aromatic component to a transalkylated aromatic stream, concurrently desulfurizing by converting the sulfur-containing component to a sulfur-containing gas stream separate from the transalkylated aromatic stream.
